"A lecture hall (or lecture theatre) is a large room used for instruction, typically at a college or university. Unlike a traditional classroom with a capacity normally between one and fifty, the capacity of lecture halls is usually measured in the hundreds. Lecture halls almost always have a pitched floor, so that those in the rear are sat higher than those at the front (i.e., tiered seating), allowing them to see the lecturer. The importance of lecture halls is so significant that some schools of architecture have offered courses exclusively centered on their design. The noted Boston architect Earl Flansburgh wrote numerous articles focusing on achieving efficacious lecture hall design." - (en.wikipedia.org 26.11.2019)
