Warkworth Castle, a medieval ruin in Northumberland, England, sits on the loop of the River Coquet near the northeast coast. Its origins are a bit murky, with some attributing its construction to Prince Henry of Scotland in the 12th century. Over time, it passed through various noble families, including the powerful Percys, who added impressive features like the imposing keep. Despite facing sieges during the Anglo-Scottish Wars and damage in the English Civil War, the castle has stood the test of time. Today, it's cared for by English Heritage and remains a fascinating glimpse into England's medieval past.
