The former churchyard included the burial ground for St Giles-in-the-Fields, where many Catholics and French émigrés were buried.
It comprises a tall square tower in a decorated Gothic style, topped by a tall Portland limestone pinnacle bearing a sundial, supported by columns of pink Shap granite and grey Cornish granite to either side of four inscribed marble plaques, each topped by a trefoil Gothic arch around a relief sculpture (busts of two saints, St Giles and St Pancras, and of two allegorical figures depicting a youthful Morning with a cockerel and a more aged Night with a star and a crescent moon).
The inscriptions on four marble panels include the Beatitudes from the Gospel of St Matthew, chapter 5, verses 3 to 9, and a religious poem.
The tower stands on a square plinth of Portland stone, which rests on an octagonal base of three steps made from red Mansfield sandstone.
The structure is surrounded by iron railings which create a square enclosure, with a Portland stone animal statue at each of the four corners, two lions and two dogs.
