Gazebo Tower to the SE of Maenan Hall

The Gazebo Tower, located to the southeast of Maenan Hall, is a circular stone structure built in two storeys with a flat parapetted roof. It features rubble construction with red brick dressings around the openings. There are round-arched entrances on the west and east sides, with square window openings flanking the front (west) entrance. At the rear, external concrete steps lead to the upper floor and roof, which are enclosed by an iron balustrade.

On the north side, there is a segmental arched recess containing an inscribed plaque that reads: "In 1959 this tower, then a ruin, was restored by Christabel McLaren and Christopher McLaren. It was dedicated to Helios and to the summer of 1959 when the sun shone every day, no winds blew and no rain fell. Architect S. Colwyn Ffoulkes; Mason H.G. Griffith." The upper storey features arched windows with blind rectangular flanking lights arranged in a Venetian window style, and small-pane casement glazing. Centrally located on the front (west) side is a 20th-century oculus for the upper floor. Inside the lower space, there is a free-standing, life-sized marble statue of Helios.
