Butchers Gate, Derry City Walls (3D Model)
Butcher’s Gate was one of the four original city gates, but the structure you see here today was rebuilt in 1810. It is constructed from a mixture of buff and red ashlar sandstone and has a single elliptical-arched opening over which the walkway is humped.
