A few steps lower down the Row is a passage or alley, communicating with Commonhall Street, called _Puppet Show Entry_. This passage is chiefly memorable as the scene of a most terrific explosion, which shook the city like an earthquake, on the anniversary of the Gunpowder Plot, November 5th, 1772. A large room in this passage was fitted up as a sort of Marionette Theatre,—a large audience had assembled,—the puppets were going through their strange evolutions,—when, by some appalling misfortune, eight hundred-weight of gunpowder lodged in a warehouse below suddenly blew up with a tremendous report, killing the showman and twenty-two others; eighty-three, besides, being more or less seriously injured. In remembrance of that fearful calamity, this alley has been ever since known as the _Puppet Show Entry_. Where that new range of superior houses now stands, on the opposite side of the street, was, until very recently, a fine old mansion of wood and plaster, the city residence of the Mainwarings, a notable Cheshire family. Just below we have, upon the left hand, WEAVER STREET, anciently _St. Alban’s Lane_, leading to the spot where the Church and _Monastery of the White Friars_ in times past stood. Of this monastic establishment no vestige remains, except a portion of the western wall, which is still visible from Weaver Street. The spire of this Church, which was of noble dimensions, served mariners as a landmark in steering their vessels up to the Walls of Chester. On the right side of Watergate Street is TRINITY STREET, in which is the oldest dissenting chapel in the city. It was erected in 1700, by the followers and friends of MATTHEW HENRY, the nonconformist, a learned and earnest preacher of his day, and author of the celebrated “Commentary on the Holy Scriptures” which bears his name. Passing Trinity Street, we arrive at the Parish CHURCH of the HOLY AND UNDIVIDED TRINITY, the first foundation of which is lost in remote obscurity. So early as the year 1188, we find Walter, rector of this Church, witnessing a deed relating to the Church of Rostherne, in this county. Very little, if any, of the original Church now exists; the west side is, perhaps, the most ancient portion of the structure, as it at present stands. Prior to 1811, the steeple was surmounted by a handsome spire, which, proving on examination to be in a dilapidated state, was pulled down, and the present square tower substituted. The reason for this change is not very obvious; perhaps there may have been bickerings and dissensions in the vestry as to the relative cost of the two, and the authorities thought it best to give up the _point_, in order to make matters _square_. The advowson of the Church is vested in the Earl of Derby, having previously belonged to the Norman barony of Montalt, one of the titles created by Hugh Lupus, Earl of Chester.
