 The road 's name comes from the Old English <unk> , meaning the edge of a river , as it historically ran alongside the north bank of the River Thames . The street was popular with the British upper classes between the 12th and 17th centuries , with many historically important mansions being built between the Strand and the river . These included Essex House , Arundel House , Somerset House , Savoy Palace , Durham House and Cecil House . The aristocracy moved to the West End over the 17th century , following which the Strand became well known for coffee shops , restaurants and <unk> . The street was a centre point for theatre and music hall during the 19th century , and several venues remain on the Strand . At the east end of the street are two historic churches ; St Mary le Strand and St Clement Danes .
