That includes Valle Crucis Abbey in Llangollen (pictured).
Following Monday night’s 3-0 victory against Russia, which also placed Wales at the top of its qualifying group, Ken Skates said: "We entered this competition with a real feeling that qualification was just the start for this group of players and we were right.
“From fan behaviour to Wales’ performance on the pitch, this tournament has captured the hearts and minds of this country and really helped to showcase to the rest of the world what Wales is truly capable of.”
Earlier this month Mr Skates, who is also responsible for Major Events and Elite Sport in Wales, said he would be delighted to offer free entry to Cadw’s historic castles and monuments on June 26 if the Team reached the final 16.
Following Monday’s result he said: “We waited 58 years for this opportunity but it was certainly worth the wait.
“This has unquestionably been our Year of Adventure so far and long may it continue. I am pleased to confirm that not only will our castles remain illuminated in red but also, this Sunday, everyone will have the opportunity to visit our directly-managed Cadw sites for free.
“I hope the people of Wales will take full advantage of this opportunity and enjoy a thoroughly fun, informative and fulfilling day out to help celebrate the success of our national football team.”
There are 24 directly-managed Cadw sites in Wales where the special offer applies.
With more than 130 sites to explore across Wales, further information about all of Cadw’s castles and properties can be found on the Cadw website
