Quite unusual, this church: its tower, its cruciform plan and - that I’ve not seen before - it’s oriented SW-NE. (And why not??) Inside, it’s peaceful calm, welcoming and with a cared-for atmosphere. Go visit if you’re passing.

Great: there’s also a refill station for empty water bottles!

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!

A great place to view western Pembrokeshire. The bridleway descent to the north west is very overgrown though.

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
