St Mary's Church is an Anglican parish church in Beverley in the East Riding of Yorkshire, England. It is designated a Grade I listed building. History St Mary's was established in the first half of the 12th century as a daughter church of Beverley Minster, to serve Beverley's trading community. It is a cruciform church, 197 feet in length, with aisled nave and chancel, south transept with east aisle, north transept with east chapel and crypt below, northeast chapel with adjoining sacristy and priests’ rooms above, and a crossing tower. A few 12th and early 13th century fragments remain scattered throughout the church. These are numerous enough to determine that by the mid-13th century, the church consisted of an aisle-less chancel and transepts, an aisled nave, and probably a crossing tower. Systematic rebuilding began in the late 13th century, during the Decorated period, when a large chapel was added on to the east side of the north transept. This was followed by the addition of a south aisle to the previously aisle-less chancel, in conjunction with a widening of east aisle of the south transept. The nave aisles were completely rebuilt in the early 14th century. In the 1330s or 1340s the chancel was given a north aisle, the three easternmost bays of which were made into a superb chapel with Flowing tracery and a tierceron-star vault. The mouldings of the tracery, windows, vault, and piers all merge fluidly with each other, unifying the space. The mouldings of the vault ribs on the north wall spring from the floor and form fluted columns without capitals, and on the south wall spring from the column capitals, intersecting and running through the arcade mouldings. Building work at St Mary's ceased in the mid-14th century, as in so many cases throughout England, because of the Black Death. It did not resume until , when the west front was rebuilt in the Perpendicular style and a Perpendicular clerestory was added to the nave. The south porch and a clerestory for the chancel followed in the early 15th century. The transepts were rebuilt with clerestories in the mid-15th century; the Early Gothic arches were reused, but set on new piers. Bequests for this work were made in 1451–3, and further bequests in 1498–1500 funded the rebuilding of the west end of the nave aisles. Also installed throughout the 15th and into the 16th centuries were
