Grantham is a borough and market-town situated on the side of the river Witham, on the ancient Roman road called Ermine-street. It is 24 miles S. by W, from Lincoln, 111 N. by W. from London.

The church is a magnificent edifice, partly in the early, and partly in the decorated style of English architecture, dedicated to St. Wulfran. It is probable that an earlier building stood upon its site; as an endowment by Hugh, bishop of Lincoln, is recorded in 1100. The present structure consists of a nave with spacious north and south aisles, lighted by large handsome pointed windows. The steeple at the west end is a quadrangular tower engaged in the lower stages. It comprises three stories, the first of which is lighted by one mullioned window on each side; the second by pairs of windows, with pointed arches; and the third by one large window, with two smaller lateral ones, having triangular heads. At each angle of the parapet, which is pierced with quatrefoils, is a hexangular crocketted pinnacle. Over this rises in beautiful proportion an octagonal spire, ornamented with crockets in the angles, and at three several distances encircled with windows having triangular heads. The height of the tower to the battlements is 135 feet, and thence to the weathercock 138, making together 273 feet. The nave, including the chancel and side aisles, is inside 116 feet in length and 80 in breadth.

The tower communicates with the nave and aisles by three finely-pointed arches; and the interior of the church displays great variety in the piers and arches which support the roof. The chancel has a range of small clerestory windows, and a stone screen of exquisite design.

Under the eastern part of the church is a crypt, which belonged probably to the earlier structure. It is used now as a charnel-house.

There are several fine monuments in this church: one is to sir Thomas Bury, lord chief baron of the Exchequer, in the time of George I.; another to sir Dudley Ryder, lord chief justice of the Kings' Bench, who died 1756.

The font is a handsome specimen of ancient sculpture. It stands upon a pedestal of two steps. The shape is octangular. The base of the shaft is ornamented with heads and alternate roses. On the shaft are statues of various saints placed in niches, and round the font, under crock. etted canopies, many figures in basso relievo. These are said to represent the seven sacraments.

The vestry contains a library left by the will of Dr. John Newcombe, master of St. John's college, Cambridge, who was a native of Grantham. This, however, is not the only library belonging to the church. Over the south porch there is a collection of books, formerly secured by chains, but now, according to Lewis, nearly destroyed by time and neglect.
