It extends over an area of 10 square miles. The surface becomes elevated towards the centre. The soil is not rich, but has been much improved, and is now well husbanded. This parish is in the presbytery of Haddington and synod of Lothian and Tweeddale, in the patronage of the Earl of Hopetoun and the crown. The church has been lately rebuilt. Here are four non-parochial schools, a library, and two friendly societies. The old church of Gladsmuir was built in 1695, when the place was erected into a separate parish. Coal, ironstone, and freestone are worked, and limestone and fire-clay occur in great plenty. The road from Edinburgh to Berwick, and the North British railway, pass through this parish. George Heriot was born here, and Robertson, the Scotch historian, was some time incumbent of the parish. The principal landowners are the earls of Wemyss, Haddington, and Hopetoun, and the Bailie of Lamington. A circular rising ground at the Laird's Dyke is the only trace of the ancient mansion of the Douglases of Longniddry, who entertained John Knox when forced to retire from St. Andrew's. The ruins of Knox's chapel exist near Longniddry."
