Monasterevan, the Venice of the west

This is a considerably expanded and updated version of an article I wrote years ago, with lots of photos. There are traces of three lost waterways to be seen in Monasterevan (my favoured spelling) and lots of other interesting waterways artefacts as well. There is even an operational puzzle: in the days when boats locked down from the canal to the Barrow, and locked back up on the far side, how were they propelled (and controlled) when crossing the river?
