Beautiful old pub! Stopped here after a hike & it was fascinating inside, plenty of locals, of course a lot of tourists (as I was!) But I'd love to come back here sometime & go there for the evening, it just looks like it gets a bit loose!

Porthgain, a small coastal village in Pembrokeshire, became an industrial hub in the 19th and early 20th centuries. The quarrying activities in Porthgain primarily focused on slate and later on roadstone. The harbour, constructed in 1851, was essential for exporting slate from nearby quarries. Initially, slate was transported to the harbour by horse-drawn tramways and later by steam-powered machinery. By the late 19th century, the industry expanded to include brickmaking using slate waste. The demand for roadstone led to the development of steam-powered crushers and large storage hoppers, which are still visible today. Despite its industrial success, the Great Depression in the inter-war period led to a decline in trade, and by 1931, the quarrying activities had ceased. Today, Porthgain is a conservation area, preserving its rich industrial heritage and attracting visitors to its historical sites and scenic beauty

Porthgain is known for its picturesque harbour and rich industrial history. The village was once a bustling industrial port in the early 1900s, primarily involved in the export of slate, bricks, and crushed roadstone. Quarry History: • Slate Quarrying: Slate was the primary industry in Porthgain from around 1850 to 1910. The slate was quarried from nearby locations like Abereiddi and Trwynllwyd and transported to Porthgain via a tramway. • Brickmaking: From 1889 to 1912, bricks were manufactured using waste from the slate operations. The large brick hoppers that dominate the harbour today were used to store crushed dolerite before shipment. • Roadstone Production: After the decline of the slate industry, Porthgain turned to producing crushed roadstone from 1889 until 1931. Today, Porthgain is a conservation area, attracting visitors with its historical charm, scenic views, and local seafood. The harbour remains active, primarily serving local fishermen and recreational boaters.

Remnants from a time gone by then ships used to be loaded with quarried materials via the structures that still remain.
