Old Cathedral School

The Old Cathedral School, now offices, dates from 1908 and is located close to Truro Cathedral. It was designed by Frank Pearson, with the associated chapter house by J L Pearson. The building is constructed of roughly coursed rubble stone with freestone and granite dressings, and has dry Delabole slate roofs with coped gable ends. A stone stack is situated over a cross wall to the rear, and over a returned gable end. The architectural style is Late Gothic.

The building has an irregular, shallow U-shaped plan. The east front is dominated by a four-storey tower with a parapet. To the left of the tower is an embattled stair turret with a pair of pointed arched, two-light, traceried windows with a hood moulding linked to the tower stringing. The tower itself has four-centred arched, three-light mullioned windows and a parapet string. The central section, set back, has a five-window range. To the right is a projecting gable end with a central external stack. The west elevation has a three-window range on the left and a two-window tower on the right. The first floor of the west elevation features transomed windows with a fenestration pattern of 4-centred arched lights, while the ground floor has flat-headed windows, mostly with transoms, and a depressed, two-centred arched doorway. The second and third floors of the tower have two pairs of four-light windows with four-centred arches.

The south entrance front uses responds of what were intended to be the interior of cloisters. These cloisters survive for approximately one and a half bays to the left of a wide doorway and one bay to the right. Weatherings for the never-completed roof are visible above the right-hand arch. The 1908 tower has two five-light mullioned windows to the third floor, one to the left and one centrally located.

Internally, there are two granite fireplaces with Gothic-style hoods, and other fireplaces have been inspected. Some original doors retain Gothic detailing.
