Thorncastle Street flats

Thorncastle Street flats is a complex of social housing apartments, designed by Herbert George Simms. Situated in Ringsend, it was constructed in the 1930s in a modernist style. There are three blocks of flats with the southernmost block having the most ornamentation. It is located on the banks of the River Dodder close to where it joins the Grand Canal Docks and Liffey Estuary.
The complex was officially named after The O'Rahilly. The name Thorncastle comes from the estate of Thorncastle which was held by the Fitzwilliam family since at least the 1500s.
