Continuing along the bastion the limit of the northern wall is soon reached. Many of the old streets in this quarter of the city are worth visiting, for in the narrow thoroughfares are some interesting old houses. In St. Mary Arches Street is the church of the same name, shut in by houses. It is one of the old parish churches of Exeter, and one that takes part of its name from the fine Norman pillars and arcade of the nave, which is the oldest in the city. In the south aisle is a chantry containing the altar tomb of Thomas Andrews, mayor in 1505 and 1510; and who died in 1518. Mint Street, as its name implies, was associated with the mint established there by permission of William III. The coinage minted there may be recognized by the letter E placed beneath the king's head. Bartholomew Street brings us to Fore Street, a narrow and very steep thoroughfare, within which is the fine front of the Tuckers' Hall, belonging to the Incorporated Guilds of Weavers, Fullers, and Shearmen, chartered in 1490. Close at hand are steps leading down to Exe Island, which was for many years a subject of dispute between the Earls of Devon and the citizens; but on the attainder of Henry, Marquis of Exeter, in 1558, the property reverted to the Crown. On the conclusion of the Prayer-Book Riots the island was granted to the city by Edward VI, as a reward for the services it had rendered the authorities. Most of the old portions of the island have been destroyed, many of them in recent years, but an interesting specimen of a Tudor house remains with a covering of slates somewhat resembling scale armour. Shields appear in the ornamentation, one of them bearing the Tudor rose. At one time this style of wall covering was very common in Exeter, but the example in Exe Island is the only one now remaining. On the south side of Fore Street stands St Olave's Church, where, according to Domesday, a church with the same dedication existed before the Conquest. It is said traditionally to have been built by Gytha, Harold's mother, in order that masses might be said for the souls of her son and Earl Godwin. William I gave the church to the monks of Battle Abbey, in whose possession it remained until the Reformation. More than a century later St. Olave's was lent to the French Huguenot refugees, many of whom settled in Exeter where they established an important woollen industry. The present church bears few indications of antiquity, beyond some Norman arches and a little early carving in the tower.
