Martello tower
The most prominent feature on Shenick Island is a Martello tower. It is possible to climb into this with some effort. The martello tower is relatively intact however any wooden floors are long gone. The spiral staircase is still intact and access to the tower roof is possible. The old cooking grate is still intact but the iron grate is heavily rusted. The tower is exactly 1 mile from the great windmill in Skerries and approximately 1 mile from the Monument on Strand Street and the Martello tower on Red Island.
