St. Austell Seventh-Day Adventist Church

A modest brick chapel on the edge of St. Austell, this Seventh-Day Adventist Church is the sort of place most visitors drive past without noticing. Unless you're specifically interested in how different Christian denominations set down roots in Cornwall's mining towns, there's not much reason to stop. The building itself is functional rather than striking - Victorian-era architecture with none of the soaring drama of the Anglican parish churches dotted across the county.

Worth knowing: the church keeps irregular opening hours, so ringing ahead from Charlestown (just a short drive away) makes sense if you want to look inside. It's free to visit, which costs nothing but your time. Realistically, twenty minutes covers it - you're not talking about a major detour.

For a church visit to feel worthwhile during a park holiday, you'd usually want something with either serious historical weight or architectural wow factor. This has neither. That said, if you're camped at East Crinnis Holiday Park or Par Sands and you've got an interest in industrial Cornwall and religious history, you might find it worth a quick look on a rainy afternoon. The area was shaped by tin and clay mining, and small chapels like this one tell part of that story. Just don't expect it to be the highlight of your trip. The real attractions - Lost Gardens of Heligan, the coast paths, Pentewan Sands itself - will keep you far busier.
