The Sleigh Bay entrance to the Rideau Canal is a spectacular sequence of eight locks climbing 25.3 metres from the river to the plateau above. This watercolour of circa 1838 shows the entrance from the Quebec side of the Ottawa River. Construction work on the canal began here in 1827. Alongside the locks can be seen two stone buildings - the Commissariat on the west side (here, to the right) and the Ordnance (or Royal Engineers) Building on the east side. The former survives today as the Bytown Museum. Barracks Hill, just to the west of the locks, is now the site of the Canadian Parliament Buildings, built starting in 1859.
