Mid Calder (Scots: Mid Cauder) is a town in West Lothian, Scotland. It is located on a steep hill overlooking the River Almond and Calder Wood, around 15 miles (24 km) west of Edinburgh. The town has been on a major crossroads since its origin some time in the eleventh century.
James Sandilands received the lands of Calder from his brother-in-law, William IV, Lord of Douglas, in the 14th century. During the Wars of Scottish Independence, Sir James de Sandilands distinguished himself in the wars against the English. For his services he was rewarded with a royal charter of his lands by David II of Scotland. James was well connected and married Eleanor, the only daughter of Sir Archibald Douglas, Regent of Scotland. The gift included extensive estates in what is now West Lothian, and the Barony of Calder. After the Reformation in 1560, Sir James Sandilands, the head of the Sandilands family, was created Lord Torphichen. Since 1348 the family seat has been at Calder House, near to the middle of the village.
