Rushton Triangular Lodge, Kettering, Northamptonshire

An extraordinary piece of symbolic architecture sits along a lonely country lane, about a mile from the village of Rushton. From a cursory glance at this small but ostentatious building, it bears all the hallmarks of being nothing more than a folly. Upon a closer inspection of both its structure and its history, however, a deeper explanation for the existence of this building gradually reveals itself.

The Rushton estate was the principal seat of the Tresham family from 1437, and a large, country manor house was built in the late 15th century. With a staunchly Catholic background, Sir Thomas Tresham experienced a difficult and troubled life during the last two decades of the 1500s, and was imprisoned for much of the time because governments of the day felt threatened by his religious persuasion. It was during his prolonged captivity that Sir Thomas formulated the idea of making a covert declaration of his faith, having already smothered his cell walls with symbolic letters, dates, numbers and other religious scribbles.

It was not uncommon for the Elizabethans and Jacobeans to incorporate 'messages' within their elaborate buildings, but to emblazon a house with so many clear references to the Trinity was an outrageous notion. Nonetheless, on his release in 1593, Tresham began designing the triangular lodge, as something of a shrine dedicated to his long suffering. The result was this small, colourful house adorned with dates, emblems, biblical passages, shields and skilfully carved gargoyles. Constructed on the basis of an equilateral triangle, the symbolism is apparent throughout the entire building, and all features relate back to the Holy Trinity and the Mass. On the three walls, there are three windows on each of the three floors, three roof gables, and even a triangular chimney adorned with Tresham trefoils.

Inside the house is remarkably plain, providing compact and simple accommodation for a gamekeeper or someone of similar status. The building is often referred to in the Rushton estate documents as The Warryners Lodge. Not a lavish palace, an impressive stately home, or a romantic country manor house, just a bizarre little dwelling created by the imaginative, perhaps slightly eccentric, mind of a devout Catholic man. Even if the religious connotations seem a bit heavy going and difficult to interpret, the fascination of identifying some of the emblems, and trying to understand how Thomas Tresham's mind worked, invites a compelling investigation of the lodge.
