St Catherine’s Island homes a fort

St Catherine’s Island

Lying just off the coast of Tenby is St Catherines island which has been used as a filming location for the popular BBC series Sherlock. However, St Catherines Island was originally home to a small chapel which later became the property of the Corporation of Tenby who later sold it to the War Office in the 19th Century for only £800. During this time the island took on a much more important role in Tenby’s life.

In 1867 it was decided that the island needed to be worked on the make a secure fort that would provide protection against incomers from the sea. By the end of the decade, the War Office had established a garrison with a total of 9 guns and 100 men. The army and the navy both held control of the island until the early 20th Century until the Windsor Richards family bought it and converted the fort into their summer home. St Catherine’s Island even became a small zoo in 1968 but in 1979, this relocated and the island has since stood empty.

Caldey Island is a Holy island

Caldey Island

In the 6th Century Monks first came to Caldey. Pyro, the first abbot is remembered in the island’s Welsh name, Ynys Byr (Pyro’s Island). Pyro was followed by St Samson, from the Celtic monastery at Llantwit Major. Viking raids may have ended this settlement in the 10th Century. In the 12th Century Benedictines from St Dogmaels, Pembrokeshire, set up a priory on the island. They remained until the Dissolution in 1536. In 1906 pioneering Anglican Benedictines purchased Caldey and built the present Italianate style abbey which now towers above the village. They were received into the Roman Catholic Church in 1913. Their stay was relatively short, financial difficulties forcing them to sell in 1925.

The present monks of Caldey Abbey are Reformed Cistercians. They came from Scourmont Abbey in Belgium in 1929, re-establishing the strong Cistercian tradition in Wales. (13 monasteries before 1536). It was the development of the perfume industry and tourism that eventually brought them financial independence.

Even when their numbers became dangerously low in the early eighties they stayed spiritually strong. Following that lean period, there was a steady stream of new vocations, and the community began to grow again. In more recent times, however, some of the older members have passed away, and vocations have been fewer, leaving the numbers once more quite low. Although somewhat reduced in numbers, the monks continue to practice their vocation of cheerful faith and robust prayer and to thrive in their spiritual and community life.

You can enjoy a visit to the picturesque Caldey Island. This is one of Britain’s holy islands. You can get here on a 20-minute boat trip. This remote and pretty island is a haven of tranquillity and peace. The monks and islanders are pleased to welcome day-visitors to share the delights of their island home throughout the summer season.

    I am searching for my childhood girlfriend – Valerie Scheifla. My last letter from her was in July 1958. I knew her in Uniontown, Pennsylvania after the war. Her family then moved back to Tenby.
    Last Known address was Calvesland Farm, Manorbier, Tenby. Her brother’s first name was Edward or Edwin.
    When we were 6 or 7 we always walked home together from our Uniontown elementary school. It would be wonderful to find her again now that we are both 78 years old. (Born in 1944)
    I appreciate any help you can give me. Mildred Schenck Hardman, Great Falls, VA USA 22066
