Porthclais, Medieval harbor in St Davids Peninsula, Wales.
Located on the southwestern tip of St Davids Peninsula, Porthclais features stone lime kilns and an ancient harbor wall within protected ecological grounds.
The harbor, constructed in the 12th century, served as a critical trading point for coal, timber, and limestone, with the first recorded trade dating to 1385.
The inlet appears in the medieval Welsh literature collection Mabinogion, connecting the maritime heritage to early Welsh storytelling traditions.
The National Trust car park provides access to the harbor, which accommodates 50 small boats and includes a slipway for launching kayaks and dive craft.
The stone lime kilns remain intact on both sides of the harbor, reflecting the industrial processes that shaped the agricultural development of Pembrokeshire.
