The Logans flourished in their eyrie above the Loch of Restalrig, and intermarried with the best houses, Sinclairs, Ogilvys, Homes, and Ramsays of Dalhousie. It may be that some of them sleep under the muddy floor of St. Triduana’s Chapel, in the village of Restalrig, at the foot of the hill on the eastern side of their old château. This village, surrounded by factories, is apparently just what it used to be in the days of James VI. The low thick-walled houses with fore-stairs, retain their ancient, high-pitched, red-tiled roofs, with dormer windows, and turn their tall narrow gables to the irregular street. ‘A mile frae Embro town,’ you find yourself going back three hundred years in time. On the right hand of the road, walking eastward, what looks like a huge green mound is visible above a high ancient wall. This is all that is left of St. Triduana’s Chapel, and she was a saint who came from Achaia with St. Regulus, the mythical founder of St. Andrews. She died at Restalrig on October 8, 510, and may have converted the Celts, who then dwelt in a crannog in the loch; at all events we hear that, in a very dry summer, the timbers of a crannog were found in the sandy deposit of the lake margin. The chapel (or chapter-house?), very dirty and disgracefully neglected, has probably a crypt under it, and certainly possesses a beautiful groined roof, springing from a single short pillar in the centre. The windows are blocked up with stones, the exterior is a mere mound of grass like a sepulchral tumulus. On the floor lies, broken, the gravestone of a Lady Restalrig who died in 1526. Outside is a patched-up church; the General Assembly of 1560 decreed that the church should be destroyed as ‘a monument of idolatry’ (it was a collegiate church, with a dean, and prebendaries), and in 1571 the wrought stones were used to build a new gate inside the Netherbow Port. The whole edifice was not destroyed, but was patched up, in 1836, into a Presbyterian place of worship. This old village and kirk made up ‘Restalrig Town,’ a place occupied by the English during the siege of Leith in 1560. So much of history may be found in this odd corner, where the sexton of the kirk speaks to the visitor about ‘the Great Logan,’ meaning that Laird who now comes into the sequel of the Gowrie mystery. For some thirty years before the date of which we are speaking, a Robert Logan had been laird of Restalrig, and of the estate of Flemington, in Berwickshire, where his residence was the house of Gunnisgreen, near Eyemouth, on the Berwickshire coast. He must have been a young boy when, in 1560, the English forces besieging Leith (then held by the French for Mary of Guise) pitched their camp at Restalrig.
