From
@Badger_Boom 's sublime above, to the ridiculous, although this church is designated Grade II*.
Apologies for bike being out of shot, the actual ride is posted in "Your Ride...."
So, its essentially Italian Futurism in the town of Amlwch on Anglesey, designed c.1937 by Giuseppe Rinvolucri, reinforced concrete. Not able to get inside so got a pic through one of the side port-holes
Like the name though, 'Our Lady Star of the Sea'.
I also found a 1947 photo of the church in its original setting and pre-frankly awful-renovation
Its amazing what you stumble across in the oddest of places
