Historic sites across south Wales are offering free entry, events and guided tours this September as part of the annual Open Doors initiative, part of the broader European Heritage Day festival.
The event highlights the rich cultural diversity across Europe and offers people of all ages the chance to connect with history, experience Wales' heritage and discover the stories that have shaped the nation.
Tredegar House and Llandaff Cathedral
Tredegar House, cared for by National Trust Cymru, is one of the most significant late 17th-century houses in the British Isles, set within 90 acres of gardens and parkland. It features a second-hand bookshop and the Brewhouse café, which serves seasonal and locally sourced menus with profits going back into conserving the house. Free entry to the Mansion House and Gardens is available on Sunday, September 7th.
Llandaff Cathedral in Cardiff has been a site of Christian presence since Saint Teilo in the 6th century, with the present building dating from around 1120. It underwent major restorations before suffering devastation in 1941 from a landmine explosion. Various school visits, tours and demonstrations will take place for Open Doors.
Laugharne Castle and Oxwich Castle
Laugharne Castle in Carmarthenshire, where Dylan Thomas wrote Portrait of the Artist as a Young Dog, has a history dating back to the 13th century. After years of decay, Elizabethan courtier Sir John Perrot transformed the stronghold into a stately residence in the late 1500s. Perrot was later convicted of high treason and died in the Tower of London in 1592. Cadw now cares for the site, which includes medieval towers, a Tudor mansion and 19th-century ornamental gardens.
Oxwich Castle on the Gower was built by the Mansel family in a courtyard style, with a mock-military gateway and a multi-storey extension featuring an elegant long gallery. The family left after a few decades, having also owned Margam Abbey and Old Beaupre Castle.
Margam Stones Museum and Mansion House
Margam Stones Museum in Neath, located inside Margam Park, houses a collection of nearly 30 inscribed stones and crosses, some dating from sixth-century Wales. The site is free to visit across several dates in September.
Mansion House in Swansea, built in 1856 as a private home called Brooklands, has been the Lord Mayor's official residence since 1922. It retains original Victorian features including a mahogany staircase, stained-glass window and Italian marble fireplaces.
St. Illtud's Church and Dyffryn Gardens
St. Illtud's Church in Llantwit Major was founded around 500 A.D., making it one of the oldest Christian sites in Britain. Cadw describes it as a Grade I listed building of exceptional national interest. The church includes the East Church, the West Church and a restored Galilee Chapel displaying Celtic crosses from the 8th to 10th centuries.
Dyffryn Gardens in Newport is a 55-acre site showcasing Edwardian garden design, including a great lawn, Pompeian garden, Reflecting Pool, glasshouse and arboretum. A Log Stack natural play area offers children the chance to balance on trees and jump between log stepping stones. Free entry is available for Open Doors.
Ewenny Priory and Neath Abbey
Ewenny Priory, founded in 1141 by Maurice de Londres, features some of the finest Norman Romanesque architecture in South Wales, with the church, presbytery and transepts as highlights. The priory's hefty defences remain intact, and the Norman nave is still used as the local parish church.
Neath Abbey, founded in 1130 by Sir Richard de Granville, was one of Wales's wealthiest abbeys by the late 13th century. As part of Cadw's Open Doors event, an extended free tour led by guide Bill will explain the site's history, including the Norman advance, the suppression of the monasteries and the early stirrings of the Industrial Revolution.
St Margaret's Church
St. Margaret's Church in Cardiff, commissioned by the 3rd Marquess of Bute and built in 1870, is Grade I-listed. The mausoleum, built between 1881 and 1886, houses the tombs of the Bute family. Visitors can join guided tours of the church and mausoleum, go up the tower if weather allows, and take part in a quiz trail for children.
