What is the full name of the place that was closed in 1970?  Answer the above question based on the context below:  Before the 1760s, Westgate consisted of only a farm, a coastguard station (built 1791 and still standing in Old Boundary Road) and a few cottages for the crew that surrounded it. These were located beside the coast at St Mildred's Bay, named after Mildrith, Thanet's patron saint and a one-time Abbess of Minster. The town inherited its name from the Westgate Manor, which was located in the area in medieval times. In the early 20th century, the remains of a Roman villa were discovered in what is now Beach Road, where a stream once used to flow. Fresh water can still be seen rising from the sand at low tide. During the late 1860s, businessmen developed the area into a seaside resort for the upper to middle-classes. A stretch of sea wall, with promenade on top, was constructed around the beaches at St Mildred's Bay and West Bay, and the land divided into plots to be sold for what would become an exclusive development by the sea for wealthy metropolitan families  within a gated community, rather than for occasional tourists.

The demands of the increasing population led to the building of the parish churches of St. James in 1872 and St. Saviour in 1884. St. Saviour's was designed by the architect C.N. Beazley. In 1884 it was reported that Essex, on the other side of the Thames Estuary, was hit by a tremor so large that it caused the bells of St. James' Church to ring. In 1884, ownership of most of the resort passed to Coutts Bank, after the previous proprietors had gone bankrupt.Around twenty schools were opened during the late 19th century, although many had only a few pupils or closed within a few years. The largest of the schools were Streete Court School, Wellington House Preparatory School and St Michael's School.Wellington House was established in 1886 by two clergymen, the Bull brothers. It closed in 1970 and was demolished in 1972. Notable old boys included Doctor Who actor Jon Pertwee and...
