Conwy Castle

Conwy Castle stands as the ultimate medieval fortress among Edward I's Iron Ring, with eight mighty towers and 1,400 yards of intact town walls forming a complete defensive circuit. Completed in just four years (1283–1287) at a cost of roughly £15,000, it offers a raw, authentic experience that Leeds Castle (#9) cannot match—trading parkland ease for martial grandeur. The 30% steeper climb to the battlements rewards climbers with sweeping views over the Conwy estuary, a vista no moated rival can replicate. At £30, entry is 7% higher than Leeds, but the immersive history—including original arrow slits and a Great Hall—makes it the superior stronghold for medieval purists. The site also retains 90% of its original curtain walls, a statistic that Leeds cannot claim.
