Owain Glyndŵr Day: Kids Go Free at Welsh Castles on 13 Sept

Families can visit Cadw-run castles and historic monuments across Wales with free entry for children and young people under 17 on Sunday, 13 September. The one-day offer marks Owain Glyndŵr Day, with additional celebrations confirmed at Castell Harlech and Castell Cricieth.

The Welsh Government announcement applies to Cadw-run monuments throughout Wales. Families do not need to limit their visit to the two castles hosting highlighted activities, although the published information does not provide a complete list of participating sites.

Free entry across Cadw’s Welsh monuments

The admission offer covers visitors under 17 for one day. Cadw hopes it will encourage families to explore the historic places connected to Glyndŵr’s uprising and the wider story of Wales.

Several castles included in Cadw’s collection have direct links to that conflict. Caernarfon, Coety, Dinefwr and Kidwelly castles were among the sites placed under siege during the rebellion, giving families a chance to see locations associated with events that began more than six centuries ago.

Owain Glyndŵr is widely regarded as the last native-born Prince of Wales. His supporters declared him Prince of Wales on 16 September 1400, the date now commemorated annually as Owain Glyndŵr Day. The proclamation also marked the beginning of an uprising against Henry IV’s rule that continued for about 15 years.

Harlech parade and costumed Cricieth tours

A parade is planned at Castell Harlech, a site that became central to Glyndŵr’s campaign. After its capture, the castle served as a principal residence for Glyndŵr and his family, and he held his parliament there during the period from 1404 to 1409.

Castell Cricieth will offer costumed guided tours, adding a live interpretation element for visiting families. These are the two specific event highlights identified in the announcement, while celebrations are also expected at several other locations.

Culture and Sport Minister Heledd Fychan said the free-access day was intended to bring history to life for younger generations. Cadw chief executive Dr Kate Roberts said the organisation hoped children would experience first-hand the varied history represented by the monuments in its care.
