St Andrew's R C Church, Greenock, Paisley Diocese

The sandstone facade of St Andrew's rises up from Greenock's steep streets with the kind of Victorian confidence you don't see much anymore. It's a proper Catholic church, built in that solid mid-19th century style when they really meant business with their architecture. Step inside and you're hit with the scale of it - soaring ceilings, intricate tilework, and stained glass that catches the light differently depending on what time you visit.

This is one for people who actually care about ecclesiastical architecture rather than casual tourists doing a quick tick-box tour. The craftsmanship rewards a proper look. If you're staying at Rosneath Castle Caravan Park or Hunters Quay Holiday Village - both strong choices just up the coast toward Helensburgh - it's worth the short drive down to Greenock to see this. Gives you a sense of the area's industrial heritage and the communities that built something this grand.

You won't spend hours here, but thirty minutes inside is time well spent. Free to enter, naturally. Go on a clear day if you can - the interior light makes a real difference. It's the kind of place that reminds you churches were once genuine landmarks in their towns, not just buildings that happen to be old.
