This is a most graceful church, standing on a corner site within the village, but seen first across the delightful park. A tower, with a slender set-back spire, rises up at the west end. The nave, heightened with a battlement clerestorey, has no aisle on the south side making the body of the church appear tall. This effect is further emphasised by the pointed windows of the nave and steeply gabled south porch.
The chancel and south porch both date from the 19th-century but the rest of the church dates from the Decorated and Perpendicular Gothic periods. That is, apart from the splendid south doorway which is the earliest surviving part of the church and is late Norman. The bold semi-circular head has three decorative orders including one with vigorous zig-zag motif. The door itself, although Victorian, is also worth examining with its long strap hinges and pierced ventilation panel at the base.
Inside the church has a lovely anitiquarian feel. The congregation sit in wood-grained box pews. This can be advantageous in winter as each has its own fan heater! The squire and his family sit in a more decorative family pew raised up on the north aisle.
Other joinery details worthy of note include the 18th-century panelled pulpit with fluted corner pilasters. On the front a finely carved Whichcote coat of arms. Of a similar date are the oak altar rails with turned bobbin blusters.
The North aisle contains the site of the Whichcote family tomb with a raised platform surrounded by early 18th-century railings.
There are other memorials to members of the Whichcote family, including a large white marble plaque to Marian Lady Whichcote who died in 1849. She is shown in side relief seated with a book and a lamp standard which has a coiling snake - the symbol of eternity. The sculptor was T. Campbell. In the nave is a granite monument to George Bass who discovered the Bass Strait between Tasmania and Australia. He was born at Grange Farm in Aswarby Parish and baptised in this church. This would have been in the early round tub font which dates from the late 12th-century. It is clasped by four squat piers with spread out leafy capitals. The oak lid is modern and topped by a winged bird on a ball finial.
The stained glass in the eastern window at the end of the chancel dates from 1892 and is in memory of Sir Thomas Whichcote. It depicts scenes from the life of Christ, and in the tracery above are nine holy angels.
