Diving Bell, Grand Canal Dock, Dublin.

The Diving Bell was designed by the port engineer Bindon Blood Stoney (1828 to 1907) and built by Grendon and Co., Drogheda. It was delivered to the Port in 1866, entered service in 1871 and was used in the building of the Port's quay walls until 1958. The Bell has recently been refurbished and visitors can now walk through the structure's interior. http://www.dublindocklands.ie/living-docklands/things-do/sightseeing/diving-bell Source: Objaverse 1.0 / Sketchfab
