THE TOLL COLLECTOR’S HOUSE AT THE RYEWATER AQUEDUCT ON THE ROYAL CANAL
The Royal Canal, which linked Dublin to the Shannon, was fully completed in 1817. By 1794 it passed through Leixlip at the insistence of the Duke of Leinster who lived at Carton Estate. This meant the canal had to cross the Rye water valley, 85 feet below the level of the canal. In order to do this the Rye Aqueduct had to be built over the Rye Water.
