In the past I described this as a laneway at the side of Kevin Street College but as the building this is no longer a valid description. In fact, as I only discovered a few minutes ago, it was never an accurate description  because South Church Lane is the the laneway that was at the side of the college. 

Some historians claim that Liberty Lane off Lower Kevin Street once extended all the way to the canal at Portobello. However, today it does little more than connect Lower Kevin Street to Camden Row but of course it does provide back entrances to a number of pubs and restaurants. According to the 1862 Dublin Street Directory it went from Kevin-street Lr to Camden-row.
