We have visited Harlech and there is a post already about our visit to Harlech castle but it is written before my partner started writing as a historian so it won't be the same as the Conwy or beaumaris castle that I posted a link to last month.

There is probably a plan to revisit and rewrite Harlech castle but I'm not aware of it yet

Edit. Beeston Castle, not beaumaris. Although I think there is a beaumaris castle post on the blog
