St. Patrick’s Isle is also called Sodor.

The castle encloses 2.02 hectares, with the entrance to the south of the island via a causeway. The site includes, Flanking Towers, Battery, Belfry Tower, St Patrick’s Chapel, Guard House, Govway Tower, St German Cathedral, Crypt and old Reliquary of St German, Gatehouse which housed a portcullis, Gate Pillars, Magazine, Half Moon Battery and an Armoury. (Isle of Mann Guide 2021).

Peel Castle, and St. Patrick’s Island, has a vast history – one which began in prehistory. Archaeologists have uncovered an assemblage consisting of microliths (really small stone tools), core axes and axes dating from the Mesolithic period – 9000-4300BC. A permeant late Bronze Age settlement as well as some Iron Age round houses have also been uncovered demonstrating that the island has held a significant position in the history of the Isle of Man.

Around 441 AD it has been suggested that St. Patrick first set foot on the small island, hence its name. And in the 6th to 8th centuries a small monastic settlement developed. In around 550 Irish missionaries came ashore led by St. Germain. Legend states that he stopped three plagues – venomous beasts, magicians and invisible devils (Allpress 1867). Makes you wonder exactly what was happening in the area at the time!

The Norse, under the rulership of Magnus Barefoot at around 1098, understood the significance of the site and they took the island and constructed a small timber fort. Archaeological finds include a mound believed to be the remains of the first Norse fort; on the eastern side of the island a section of rampart was investigated and found to date from the Norse period; and finds from this period have been found in a number of graves. One grave was of significance and believed to be that of a high status woman who was buried with necklace of 60 amber and glass beads and some silver coins. Also uncovered has been a hoard of Hiberno-Norse coins dating from around 1040 when it is believed they were hidden in one of the small chapel buildings.

Following are some basic details of the remains and structures on St. Patrick’s Isle –

Gatehouse – This was added in around 1377 when the Montacute family held the island. It consisted of 3 floors. The ground floor was used as a guardroom and the upper two floors were used for accommodation and include fireplaces. The top was battlemented. The gatehouse was protected further by a barbican which stood in front of it.

Curtain Wall – It has been recorded that the curtain wall was constructed in the 13-14th centuries, however archaeological investigations are saying it was added in the 15th C. It was extended and refurbished during the 15th C. I have included the early dates in the timeline as this is given by a number of sources. It still requires further investigation to find the more likely dating of its structure, so until then, I shall leave them both here!

The Round Tower – Situated on the highest point of the island it was part of the original monastic buildings and dates from between c.800-1100 AD. It measures c.50.2m high, has a base circumference of 13.56m and an internal diameter of 1.8m.

The tower was entered through a doorway placed 2.10m above ground and would have been accessed by either a ladder or external stairway. The top is battlemented and there are four small openings located near the top. It is unsure as to what these were used for, but they are aligned to the cardinal points.

It is very similar to the Round Towers of Ireland and is believed to have been used as a refuge in times of turmoil as well as being used as a lookout tower. It may also have served as a lighthouse or signaling tower.

Small Chapels – The remains of three small chapels are near the round tower and it believed that these date to the first Christian settlement on the island.

St. Germain’s Cathedral – Begun in 1152 in the usual crucifix form, the central tower measured 20.12m in height. Four periods of building and repairs have been identified archaeologically dating from the 13th to the 14th centuries.

Below the main building is a barrel vaulted crypt measuring 10.36m x 4.87m x 2.74m, which was also used as a prison. Such well-known identities such as Warwick the Kingmaker, and the Duchess of Gloucester were held there. However, some believe that the Kingmaker was kept in the Warwick Tower, hence its name.


Peel Cathedral Crypt.

The tomb of Bishop Rutter was located in the transept, and an old runic monument was discovered in the south side of the nave. It is not complete, and the remaining inscription is translated as stating “Asrid, Daughter of Otter”. This may be a grave marker – and could it belong to the Pagan Lady burial uncovered by archaeologists?

A cemetery in the old nave of the cathedral was used for shipwrecked mariners, those who died at sea around the island, and others who died on the island.

In the 15th century the ruins of the cathedral were requisitioned for military purposes and the turret staircase used as a lookout point. The floor of the chancel was raised.

There is an interesting story relating to pilgrims coming to the cathedral which I thought would be of interest to you

“William Cashen, late Custodian of Peel, ‘At Easter they used to come with their offerings to Peel. They used to come to Peel from Ireland and the Scottish Isles, and it was said: ‘The wind was always at the north east at Easter for the pilgrims, and that if it would be dark there would be a supernatural light from the cathedral to guide them’. I can find nothing in tradition or in history to support this account of pilgrims or priests visiting the cathedral in Peel Castle.’ (Paton 1940).

What I find interesting is that Paton makes no mention of the ‘supernatural light’!


St Germans Cathedral – Peel Castle.

St. Patrick’s Church – These are regarded as some of the oldest remains on the island and date to the early monastic site of the 8th century. It included a bell tower and a ditch encircled it. It was rebuilt around the 10th/11th century and later rebuilt again. By the mid-19th century, it was in ruins. Burials have been discovered relating to the church.

Warwick Tower – This tower is the largest tower and was constructed in the 14th century and included fireplaces. During the 16th century three of its doors were blocked in.

Believed to be the tower in which the Earl of Warwick was held prisoner. He was also thought to have been held in the crypt of the cathedral.

Hall – Built in the early 15th century it was a place for meals, meetings and everyday business that was conducted at the castle. Initially it included three rooms, but these were then divided again. There was an external staircase to the building.

The halls use changed throughout time and eventually became ruinous in the 18th century.

Fenella’s Tower – This tower was named after Fenella in Sir Walter Scott’s Peveril of the Peak. Constructed in the 15th/16th century it may have been used as a watch tower and is situated to protect the island from a mainland attack.

The Western Battery – Built in the 15th/16th century it defended the harbour.

The Bowling Green – Dating from the 16/17th century, this flat area was used for target practice and arms training. There are banks around the perimeter whose purpose was to catch any stray arrows/musket balls. Later the area was used as a bowling green, hence its name, and nowadays hosts concerts and events.

Half-Moon Battery – The battery was installed in the 16th century to accommodate cannon whose fire covered Peel beach. It was built over the Medieval cemetery.

The Armoury – Added in the late 16th century and used for the storage of weapons, gunpowder, and ammunition.

The Garrison Hall – Built at the end of the 16th century for accommodation for the garrison. The ground floor was used for working and living activities, and the first floor was for sleep and rest.

Garrison Workshops – Dating from the 16th/17th century they also included kitchens, toilets, stores and offices.

Loopholed Wall – Situated behind the gatehouse was constructed in the mid-17th century it is located between the cathedral and the half-moon battery and connecting both, situated behind the gatehouse, its main role was as the next line of defence if the gatehouse was breached. A section of the cemetery wall was removed for its construction. It gave cover for the garrison and enabled them to effectively continue to defend the site with their muskets.

These are only a few of the structures within the castle. For a more complete description and a plan of the site, with images, go to



The archaeology of the site is fascinating! The earliest evidence uncovered dates to c.8,000 years ago in the form of worked flint discovered under the Half-Moon Battery.

The outline of several Iron Age round houses have been identified within the site.

The Norse fort of Magnus Barefoot was located as well as part of the eastern rampart dating to the same period. This rampart was later backed by a turf wall in the Medieval period.

The most exciting find to date is that of a woman and called the ‘Pagan Lady Burial’. It contained a necklace of 60 amber and glass beads, also within this burial were silver coins, a comb, shears, a knife with a silver inlay, an iron cooking spit and a sewing kit. This is regarded as being a high status burial.

Other grave types discovered on St. Patrick’s Isle include stone lintels, clinker style, shroud burials and coffins.

Other archaeological finds include,

    • Vessel glass.
    • Window glass.
    • Clay pipes.
    • Scissors.
    • Comb.

    • Ring headed pins.
    • Pottery.
    • Buckles.
    • Antler.
    • Horn.
    • Bone
    • Walrus ivory items.

    • Bird.
    • 28 species of fish.
    • Sheep.
    • Pigs.
    • Horses.
    • Deer.
    • Dog.

A few stones with crosses carved into them have been uncovered on the island and you can get a great 3D view of one by clicking the following link – Peel Castle Cross Slabs –

The site is believed to be haunted by a large black dog known as the Mauthe Dog. He haunts the guardroom and is not one to meet on a dark night! To find out what he is guarding read this poem – Stanza – Mrs John Ballantyne.

  1. An excellent article. I visited Peel Castle just prior to the first lockdown. I was on a group tour of all the possible rail-related sites and sights in Man ( v.v.v.v. good tour) but whilst the rest of the group were feeding their faces I raced over the causeway to spend a very pleasant hour or two with Peel Castle.Its a fascinating place in a beautiful setting. I also made some time to visit Rushen Castle. Again, well worth a visit.
