Places of interest

Penmon has some interesting buildings with histories to match. These buildings (the Priory and church, the dovecot and the well) are close together on the site of the old monastery. There is also an island of note nearby, Puffin Island.


Penmon Priory

The monastery (called St Seiriol's monastery) grew in size and had a wooden church building by the 10th century. This wooden building was, however, destroyed in 971 and then rebuilt in the 12th century in stone, from 1120 to 1123. The oldest parts of the Priory Church of St Seiriol date to 1140. It survived the initial Norman invasion of Gwynedd between 1081 and 1100, defended by Prince

of Gwynedd. The priory church was enlarged in the early 13th century, at the time of the Augustinian Rule. There are records for the election of Priors in the ''Calendar of Patent Rolls'' back to 1306, when one Iowerth the Prior is mentioned.Fairlamb, Rev. Neil (Rector of Beaumaris): "The Clergy of the Beaumaris Parishes" page 16. Unpublished pamphlet (available at the Church), 2007 The dining hall was on the first floor, with a cellar below and dormitory above. In the 16th century, a kitchen and a warming house were added at the east of the building. The eastern range of buildings has gone, but the southern one, containing the refectory with a dormitory above, still stands. Llywelyn Fawr and his successors made the church wealthy, giving it land. This was taken away at the time of the Dissolution of the Monasteries in 1536 but the church survived. The priory was in decline before 1536 in any event, and had only the Prior and two other members at that time. St Seiriol's Church, which was the centrepiece of the monastery, is now part of the Rectorial benefice of Beaumaris, within the

Penmon crosses

The two medieval crosses that once stood in front of the monastery (from the 10th century) are still in existence today, but are now inside the church. One cross is larger but badly weathered (because it stood outside until 1977, in a deer park). It is almost complete except for about 30 centimetres between the top of the shaft and the head. The other cross is smaller, not as weathered but has an arm of the cross cut off because it was used as a lintel for the refectory windows. It has a modern stone base unlike the other cross.


St Seiriol's Well

As was often the case with Celtic churches from this period, the church was associated with a

Puffin Island

St Seiriol established a cell and a community on Puffin Island (in Welsh, ''Ynys Seiriol'' or ''Seiriol's Island'') half a mile from the coast at the same time as he founded the monastery. There is a tower of a 12th-century church on Puffin Island still. There is a tradition that St Seiriol and perhaps

On 17 August 1831, '' The Rothesay Castle'', a wooden-hulled paddle steamer on a day trip from Liverpool, sank in very heavy seas. Of more than 140 on board, only 23 people survived. Afterwards, the Trwyn Du Lighthouse and a lifeboat station were built to try to prevent similar tragedies. The lifeboat station was closed in 1915 as it had been superseded by a lifeboat at Beaumaris. In its years of operation, the Penmon lifeboats saved at least 143 lives.

, in alternating layers. It has been moved many times due to faults fracturing and moving the beds of rock, and there are distinct lines where the beds have been moved. The cliff is approximately eight metres high; however, the distribution of limestone and shale is different near the top and bottom of the cliff. There is a gradual change of shale to limestone; near the bottom there is a lot more shale per metre of rock and nearer the top there is a lot more limestone. The cliff has been struck by several faults, causing it to look unstable; rocks fall from it from time to time. Penmon is close to the sea, thus making it prone to erosion. Quite a lot of the cliff has been eroded away, thus causing an arch to form under the cliff. The shale has eroded away faster than the limestone beds, and as such, has caused thinner beds of limestone between to collapse. This is the reason the arch is only a few metres high and does not extend further, where there are less shale beds. Faults passing through the cliff have displaced the beds, one such fault almost 23 cm, causing a ledge halfway through the tunnel. The grey-brown veined limestone quarried in the area is known as "Penmon marble".
