Leuchars (Scottish Gaelic: Luachar) is a small town near the north-east coast of Fife in Scotland. The town is nearly 2 miles (3 km) to the north of the village of Guardbridge, which lies on the north bank of the River Eden where it widens to the Edenmouth estuary before joining the North Sea at St Andrews Bay. Leuchars is 7 miles (11 km) north-east of Cupar and 6 miles (9.5 km) north-west from the university town of St Andrews. The city of Dundee is 7 miles (11 km) to the north, across the rail and road bridges that span the Firth of Tay. The town is now best known for the adjoining Royal Air Force base, RAF Leuchars, which was established in 1920, and is home to the Tornado F3s. The 12th century St Athernase Church is one of the finest surviving examples of an unaisled Romanesque parish church in Scotland, or indeed Britain as a whole, with two levels of blind arcading in the Norman style running round the exterior, surmounted by a corbel table with heads of various designs. The interior has elaborate chancel and apse arches, and a series of powerful beast-heads on the corbels supporting the ribs of the internal vaults. The nave has unfortunately been rebuilt. The apse roof is crowned by a rather incongruous small bell-tower added in the 17th century. The surrounding area was improved by drainage in the 18th century. In the 19th century, a railway station on the line from Edinburgh to Aberdeen brought increased prosperity to the town. When the branch line to St Andrews was closed in the late 1960s, Leuchars became the closest place to get the train. Since then, Leuchars railway station has been used by many University of St Andrews students.
