Wexford Harbour (Irish: Loch Garman) in County Wexford, Ireland is the natural harbour at the mouth of the River Slaney. In earlier times, the area occupied by the harbour was considerably larger than it is today, up to ten miles (16 km) wide at its widest point, with large mud flats on both sides. These were known as the North Slob and the South Slob from the Irish word slab, meaning mud.
