To commemorate Owain Glyndŵr Day, all Cadw locations across Wales are offering free entrance for children.
This particular day has been set aside to celebrate the exploits of Owain Glyndŵr, the last native Prince of Wales, and a significant historical figure.
On September 14 and 15, families will have the opportunity to explore monuments and learn about the history of Wales.
Owain Glyndŵr Day, celebrated annually on September 16, marks the anniversary of the Welsh national hero being proclaimed Prince of Wales in 1400.
This was also the start of the ‘Glyndŵr rebellion’ – a 15-year uprising that aimed to restore Welsh independence from Henry IV's rule in England.
Despite its eventual failure, the rebellion stirred identity and sovereignty sentiments among the Welsh people.
Many of Cadw’s castles including Caernarfon, Coety, Dinefwr and Kidwelly were besieged by Owain Glyndŵr during his rebellion.
Over the weekend, several events will be held in different Cadw locations.
Visitors to Castell Cricieth on September 15, for example, will hear the story of Owain Glyndŵr as they tour one of the castles he attacked.
On the same day, there will be celebrations, along with the Ardudwy Knights, at Castell Harlech, which he seized in 1404.
Visitors to Castell Rhuddlan will enjoy a session by Cadw's storyteller who will narrate Mr Glyndŵr's legend through story, music and song.
Those who fancy learning about the castle taken by Welsh princes like Mr Glyndŵr should not miss the Beaumaris Castle History tour on September 16.
Apart from marking Owain Glyndŵr Day, the 'children go free' offer is part of Cadw's 40th-anniversary celebrations, a further significant milestone in its mission to nurture Wales' historic sites.
Head of Cadw, Gwilym Hughes, said: "The cost of living is still having an impact on families so by offering free access to children across our magnificent monuments, we hope that people will be encouraged to visit Cadw locations and give children a real taste of Wales’ extensive history.
"Each Cadw location has a unique story to tell.
"Indeed, many of these shaped Owain Glyndŵr’s rebellion.
"Although he was ultimately unsuccessful in his ambition, his legacy endures at many locations, including some Cadw sites.
"These historic places are a testament to his determination and patriotism.
“We hope this weekend to commemorate his life and legacy will give an insight into our deep roots as a nation – making our rich heritage accessible to all."
