Carstairs is a village in South Lanarkshire, Scotland. Carstairs is located 5mi east of the county town of Lanark and the West Coast Main Line runs through the village. The village is served by Carstairs railway station, which is served by the Caledonian Sleeper to and from London Euston. Carstairs is best known as the location of the State Hospital. Carstairs is applied to the places Carstairs Village and the village of Carstairs Junction where the railway station is situated. The two places are two completely different villages divided by 1mi of land, a parkland area (Monteith Park) and the railway line.Carstairs Village has massively expanded since 2007 with the building of Millwood Estate (MCA Homes now defunct and completed by Cala Homes). Carstairs Village is centred on the main thoroughfare Lanark Road, off which is the original Rosemount Crescent and Avenue Road and School Road. There are further streets at Millwood Estate namely- Castledyke Way, Castledyke Lea, Castledyke Gardens, Castledyke View and Castledyke Road. The village is currently served by a Doctors Surgery, an Rx Pharmacy, a Cooperative food store, a cafe (Cafe on the green), a Car Wash and Tyre fitting workshop. There is also a pub and restaurant called the Carstairs Village Inn situated on Lanark Road whilst there is a second-hand car dealer located at the entrance of the village from the Carnwath to Lanark road. Where as Carstairs Junction has reduced in size due to social decline and because of the bad state of some of the buildings, more than half of the town has been demolished since the 1960s.
