Back in the twenties the new Functionalist Architecture
embraced all kind of new building types. New types of
schools such as the "pavilion" schools developed by
Ernst May or the "hall" schools proposed by Otto Haesler,
are just some examples of those highly creative times. In
the "hall" school of Celle built in 1927, all the classrooms
and offices are grouped around a covered central area
that serves as gymnasium and assembly hall.
