The physical environment of South Tyneside varies greatly in a small area: from the bustling riverside towns of South Shields, Jarrow and Hebburn to the urban fringe villages of Boldon, Cleadon and Whitburn; from established industrial areas at the Port of Tyne and Tyne Dock riverside to new business parks at Monkton, St Hilda's and Boldon; from the highest point at Cleadon Hills down to the River Don estuary at St Paul's and Bede's World; from traditional Victorian terraces and impressive Edwardian mansions to typical inter- and post-war suburban housing; from the remains and reconstructed gatehouse of Arbeia Roman Fort to the UK's first purpose built mosque at Laygate; from the great River Tyne to the expanse of Shields Harbour at Littlehaven; from the stunning natural coastline of The Leas and the sandy beaches, bays and limestone cliffs at Marsden Bay and Whitburn to the traditional seaside parks, amusements and funfair at South Shields seafront; and from Marsden Quarry to the Great North Forest.
