What is "drumsna"

Drumsna ( which translates as the ridge of the swimming place) is a village in County Leitrim, Ireland. It is situated 6 km east of Carrick-on-Shannon on the River Shannon and is located off the N4 National primary route which links Dublin and Sligo. The harbour dates to 1817 and was a hive of commercial waterway activity until the more northern navigation canal to Carrick-on-Shannon was opened in 1850. Today, the waterway is busy with anglers and tourist pursuits in the summer months but at a much more leisurely pace.
