Rotundas are around buildings or rooms, sometimes with a domed roof. The word “rotunda” has its origins in the Latin word “rotonda,” meaning “around”; those structures became popular in medieval Central Europe. Curves in structure consistently require just angled cuts and additional materials and technology, so these major feats of structure were initially utilized in churches, libraries, government buildings, museums and halls as showpieces.
