Stumbled across this beauty on my Jurassic Coast travels. The Geoneedle features many different types of rock to commemorate just how much history is on display in the area.
From the National Trust page:
The Geoneedle at Orcombe Point is an impressive landmark constructed of the various rock types found along the World Heritage coastline. It was commissioned from public artist, sculptor and designer Michael Fairfax to commemorate the opening of the World Heritage Site and was unveiled by HRH the Prince of Wales in 2002.
