Carn Fadryn, Iron Age hillfort in Llŷn Peninsula, Wales.
The summit reaches 371 meters in elevation and extends across five hectares of land, offering views of Anglesey and the Snowdonia mountain range.
The site contains three distinct fortification phases, with initial construction dating to 300 BC and subsequent expansions occurring around 100 BC and 1188.
The medieval castle at the summit represents one of Wales's earliest defensive structures, built after Prince Owain Gwynedd's death for his sons.
Visitors can access the site from the chapel car park, following a well-marked grass track that runs parallel to stone walls toward the summit.
From the highest point, observers can see geological formations shaped by glacial meltwater, including views of Bardsey Island and the Uwchmynydd headland.
