It developed on the north shore of the Firth of Clyde at a time when Clyde steamers brought it within easy reach of Glasgow at about 25 miles west of the centre of Glasgow by boat. Many Glasgow shipowners and merchants made their summer retreats or even permanent residences there, and this is reflected in some very grand houses along the shore. Not all have remained occupied; some were demolished and others have been converted into flats.
