tholobate

It is an octagonal tholobate pierced with 24 windows in green glass.

The spherical cupola is located on a high tholobate.

A tholobate or drum, in architecture, is the upright part of a building on which a dome is raised.

Its semi-dome has a fine stalactite structure, crowned by a small ribbed dome on a tall tholobate.

In the center, where the dome should be, is the tholobate, whose pendentives decorated with Mark and John the Evangelists.

Above the windows is the tholobate; above it tholobate rises a rough wall that hides the small dome erected on the same tholobate.

Occupying a full city block facing Lake Ontario in Kingston's downtown, the city hall is a prominent edifice constructed in the Neoclassical style with a landmark tholobate and dome.

The term also applies to the wall of a circular structure, whether on the ground or raised aloft on pendentives and carrying a dome (also known as a tholobate), and to the drum shaped segments of a column, which is built up in several courses.
