Penmon Point or Black Point

Penmon Point or Black Point (Trwyn Du) as it is also known locally is the most easterly point on Anglesey. The Point is private land currently owned by the Baron Hill estate in Beaumaris, but allow access for a small fee payable at Penmon Priory.

As you pass the Dovecote, there is a small lane on the right hand side that travels towards one of the several quarries in this area. The high quality limestone from the quarries at Penmon Point supplied the stone to build many local buildings including the Menai Suspension Bridge and the Britannia Bridge.

Penmon is derived from two Welsh words Pen meaning head and Mon being the welsh word for Anglesey

Trwyn Du lighthouse at Penmon Point was built to warn shipping in the area about the stretch of water between the Point and Puffin Island.

This body of water known as Puffin sound can be extremely dangerous.

The lighthouse which sounds a bell to warn shipping of its location in case of fog was built in 1838.

The old lifeboat station at Penmon

Birth of the Anglesey Lifesaving Association

Unfortunately the coast of Anglesey is famous for its many shipwrecks and the area around Puffin Island is no exception.

In 1831 a wooden hulled paddle steamer called the Rothesay Castle which was on a day trip from Liverpool sank near to the island, and only 23 people survived from 140.

As a result of this maritime tragedy the Anglesey Lifesaving Association was founded and opened the Anglesey lifeboat station at Penmon in 1832.

The former Penmon lifeboat station and the remains of its slip way can still be seen today.

Limestone Quarries

The area around Penmon Point is well known for its high quality limestone, which has been used to build many local buildings and structures like the Menai Suspension Bridge and the Britannia Bridge.

Many of the properties on the front of Beaumaris like the Bulkeley Hotel were also built with limestone from these once popular quarries.

The Penmon quarries have been working limestone since the sixteenth century and carried on until about 1968 where it provided limestone for the construction of the Seaforth Container Terminal.

There are two main quarries at Penmon point that have worked for limestone, they are Flagstaff quarry, which is situated on the south side and Dinmor quarry which is located on the north side of the point, this is the one believed to have supplied the limestone for the Menai Suspension and the Britannia bridges.


Facilities are quite scarce in this remote part of the Island although there is the Pilot house Café which sells the usual refreshments, tea, coffee, soft drinks and some food is available. There is also a toilet here as well, you will need to request the key from the cafe.
