You can't miss the massive 1810-built bridgehead fortifications on the western bank in County Roscommon, where heavy artillery was installed to bombard Napoleon in case he tried to invade by river. Substantial other sections of the fort remain: the adjacent guardhouse is still here and part of the redoubt and defensive wall survive, although some of it was demolished in the 1950s to allow vehicles to pass.
