Trinity Hospital

Trinity Hospital was built between 1613 and 1617, with alterations and partial rebuilding occurring in the early 19th century. The building is constructed of multicoloured stock brick, with a stuccoed front that gives the impression of an early 19th-century appearance. It is a relatively small-scale building in the Gothic style.

The front elevation is two storeys high with seven windows. It has a steeply pitched roof covered in large slates, tall stuccoed chimney stacks, and a battlemented parapet. The ends are cross-gabled with crow steps and a pinnacle on either side of the gables. The windows are 3-light casements with Gothic bars under square hoodmoulds; exceptions are the first-floor windows in the side bays, which have high, pointed hoodmoulds with stucco interlacing tracery. The central tower has an arched entrance on the ground floor and a window on the first floor, with blank arcading above. At roof level is an achievement of arms with Latin inscriptions above and below, surmounted by a clock. A battlemented parapet rises to a small spire or spike, with louvred bell openings, a flagstaff, and a vane.

Inside, a courtyard is enclosed by a range of five bays on each side, with arcaded ground floors featuring 4-centred arches mirrored in the doorways. The first-floor windows have glazing bars. Stepped gable ends are located behind the front range; the west gable incorporates a Venetian window. The rear elevation is two storeys high with seven windows, constructed of multicoloured stock brick. The windows are 3-light casement windows with stone frames and mullions, and there is a first-floor band.

The three-bay Chapel in the South range exhibits Gothic decoration from 1812, with rib-patterning to the segmental vaulted roof. Pointed windows have hoodmoulds with interlacing bars. The East (ritual) window is a 4-centred arch containing Flemish stained glass dating from the early 16th century, with decorative panels and depictions of The Crucifixion, The Agony in the Garden, and The Ascension. A monument to the founder, the Earl of Northampton, by Nicholas Stone, is also present.

Trinity Hospital, its Lodges and Front Wall form a group.
