An old house in Crooked Lane, in the parishes of St. Michael Crooked Lane and St. Martin Orgar, in Candlewick Ward.
Called "le Leden Porche," 1441, 20 H. VI., granted to John Merston (Cal. P.R. H. VI. 1441-6, p. 5).
Stow describes it as one of the most ancient houses in the lane and says it belonged sometime to Sir John Merston, 1 Ed. IV. (S. 220).
It is now called "the Swan" in Crooked Lane, possessed of strangers and selling of Rhenish wine (ib.).
Mentioned in Ch. I. p.m. 1398-9. In 1485 granted to Thomas Freeman on the attainder of John, Duke of Norfolk (Kingsford's Stow, II. 314).
The demolition of some of the buildings surrounding the church of St. Michael, Crooked Lane, in 1831 for the formation of the approaches to the new London Bridge, brought to light the remains of an old crypt of the 12th century, too far east to occupy the site of the original church. It possibly formed the crypt of this mansion (Gent. Mag Lib. XVI. pp. 55 and 56).
