About: St Mary Street/High Street

St Mary Street (Welsh: Heol Eglwys Fair) and High Street (Welsh: Heol Fawr) are major commercial streets in the Castle Quarter of Cardiff city centre, Wales, which form a major thoroughfare running south from the gatehouse of Cardiff Castle. High Street begins at the junction of Castle Street on the A4161 and ends at the junction of Church Street and Quay Street, from where St Mary Street begins until the roundabout at Callaghan Square on the A4160. In the 21st century, the thoroughfare has become the location for a wide variety of pubs, bars, restaurants, cafes and coffeeshops.
