Edinburgh has been the capital city of Scotland for around 500 years. It is noted for the volcanic crag of Arthur's Seat, and for being the seat of the Scottish Government. Because of this and the city's universities, it has a vibrant economy and social scene. Landlords provide flats to let in the city centre, encompassing the historic Old Town and the subsequent New Town, to Edwardian townhouses in the sought-after West End. In recent years the focus for property development, with an increasing influx of young professionals, partially influenced by the location of the new Scottish Government building, has been in the old harbour areas of Leith and Ocean Terminal. Higher city rents have led to expansion of the property market in Penicuik, Bonnyrigg and Midlothian towns to the south. To the west of Edinburgh are the historic towns of Linlithgow and Kirkliston, ideal for commuting, as well as the West Lothian towns of Livingston, Broxburn and Bathgate. Girlings offer retirement flats in Edinburgh for the over-60s.
