Tholobate
dome base in architecture
A tholobate (from Ancient Greek θολοβάτης (tholobátēs) 'dome pedestal'), also called a drum or tambour, is the upright part of a building on which a dome is raised. It is generally in the shape of a cylinder or a polygonal prism. The name derives from the tholos, the Greek term for a round building with a roof and a circular wall. Another architectural meaning of drum is a circular section of a column shaft.
Examples
In the earlier Byzantine church architecture the dome rested directly on the pendentives and the windows were pierced in the dome itself; in later examples, an intervening circular wall containing windows was built between the pendentive and the dome. This is the type which was universally employed by the architects of the Renaissance, of whose works the best-known example is St. Peter's Basilica at Rome. Other examples of churches of this type are St Paul's Cathedral in London and the churches of the Les Invalides, the Val-de-Grâce, and the Sorbonne in Paris.
Tholobates are also used in secular buildings: the United States Capitol dome in Washington, D.C., is set on a drum, a feature imitated in numerous American state capitols. The Panthéon in Paris is another secular building featuring a dome on a drum.

Why this record matters
“Tholobate” is worth following because a concise public description often conceals a longer documentary argument. Here, Tholobate, dome and base provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated May 31, 2026. The linked authority identifier is Q2294433. None of the 0 selected statements returned an explicit reference.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
