Near to the old Crown Fort stood the ancient parish church of St. Mary (a dependency of Dryburgh Abbey). In a Writ of c1217 an "Everardus" is recorded as pastor of Laweder, and in 1245 there was a Chapter of the Clergy of East Lothian at Lauder on Saturday after the Feast of Saint Peter, "ad vincula", when a dispute was settled between the Priory of St. Andrews and the nuns of Haddington, regarding the tithes of Stevenstoun, nr. Haddington. In this original church many of the old Lauder family were interred, including two bishops, William de Lawedre, Bishop of Glasgow and Lord Chancellor of Scotland, and Alexander Lauder, Bishop of Dunkeld. It was from this church, in 1482, that James III's favourites, including the architect Robert Cochrane, were dragged by envious nobles led by Archibald Douglas, 5th Earl of Angus and hanged from the (earlier) Lauder Bridge. The sites of the ancient kirk and the bridge from which Cochrane and his colleagues met their demise, are now within the immediate policies of Thirlestane Castle, the church some 60 yards from the west front, and the bridge some quarter-mile to the north-east.
