Located at the highest point of Signal Hill, overlooking the city and the ocean, Cabot Tower is an example of late-Gothic Revival style. Built of irregularly coursed red sandstone, it is composed of a two story, 30 foot, square structure with a three story, 50 foot octagonal tower that stands on the southeast corner of the building. The corners are buttressed at the first floor level and further emphasized through the use of heavier blocks of stone. On the main body of the building, at the top of the second story level, is a line of repeating pattern like an exaggerated dentil row or inverted crenelations. The attached tower, which houses the main entrance, is very plain with a double string course marking the divisions between second and third storys and heavy corbel tables marking the eight corners of the turret at the flared upper level. The windows on both the corner turret and the body of the tower proper are rectangular and set under heavy stone lintels.[3]
