On either side of the Northern end of the demolished viaduct is a type 23 Pillbox.
The western one is on an accessible part of the walkway
The eastern example is in a private field, so no close-up.
Pillboxes, Thorpe Thewles Viaduct

A Hamadryad being a greek mythological being that lives in a tree.
The temple is dedicated to Minerva goddess of wisdom and the arts and was originally constructed between 1754 and 1757.
The niches on each side contained busts of Homer, Virgil, Horace, Milton, Shakespeare, Ben Johnson, Dryden and Pope.
It’s fascinating to see this picture from 2004 when the site was a ruin before restoration.
