Church of St Maurice) is of Norman origin. St Mary's church was dedicated in 1311 and was originally a parish chapel attached to Plympton Priory. It has two aisles on each side of the nave, the outer aisles being shorter than the inner ones. The tower, built of granite ashlar, is visible from afar. The south porch is ornamented with carving and has a lierne vault. The outer north aisle is the earliest part of the church and the rest is mainly of the 15th century, the south aisle being the latest part. There are monuments to the Strode family, including a tomb-chest for Richard Strode (died 1464), the effigy being clad in armour. The monument of William Strode (died 1637) and his family shows husband, two wives and ten children. There is also a monument of W. Seymour (died 1801) in Coade stone and of Viscount Boringdon, the 11-year-old heir to the Earl of Morley of Saltram House who died in Paris in 1817, by François-Nicolas Delaistre. Modern Plympton Between about 1990 and 2010 Plympton has seen considerable growth as the suburban population of Plymouth has doubled. To help manage this rapid growth more efficiently, Plympton has been separated into a series of separate districts: Yealmpstone, Plympton-St Maurice, Colebrook, Underwood, Woodford and Chaddlewood. Public transport Plympton has four main bus services: routes 20, 20A, 21 and 21A, which are operated by Plymouth Citybus and services 52 and 59, which are operated by Target Travel. In the past, railway facilities were originally provided at Plympton – for goods traffic only – by the horse-drawn Plymouth and Dartmoor Railway, but their branch was closed and sold to the South Devon Railway to allow them to build a line from Exeter to Plymouth. A station was opened in the town on 15 June 1848. From 1 June 1904 it was the eastern terminus for enhanced Plymouth area suburban services but it was closed to passenger traffic from 3 March 1959 and all goods related traffic from June 1964. In addition to this railway connected to the National rail network there is also The Plym Valley Railway which is a preserved railway based at the reconstructed Marsh Mills station on Coypool Road. This was formerly part of the GWR Plymouth to Launceston branch line. The volunteer-run PVR is actively rebuilding the line between Marsh Mills and Plymbridge. Steam and diesel heritage trains run
