The longtime rift between the Museum of Contemporary Art’s board of trustees and the city of North Miami turned into a physical breakup Wednesday as the nonprofit that has overseen MOCA moved its employees out of the city-owned building and announced plans to establish a new arts organization.

The new Institute of Contemporary Art will open a temporary space in November at the Moore Building in Miami’s Design District, according to a statement from board co-chairs Irma Braman and Ray Ellen Yarkin.
