The Theater in St. Gallen was constructed between 1964 and 1968. Zurich architect Claude Paillard designed it as a sculpturally modeled exposed concrete structure on a hexagonal floor plan. The building’s space spirals upward from the entrance floor around the auditorium, with hexagonal spatial modules with different aspect ratios repeated on the various floors. The countless steps in the floor and ceiling make the movement in this concrete sculpture visible both inside and outside the building façade.

In use. Approximately 50 years after its construction, spalling and cracks were visible on the façade of the theater building, plus there was asbestos in the joints of the glazing. Furthermore, the technology also had to be brought up to date. After St. Gallen people voted YES for a credit over 50 million CHF to save and renovate the building in March 2018, the renovated building opened its doors again in October 2023.
