The building with dimensions 36x26m. considered too large for a  private home and was probably used to host a Club like the neighboring building of Poseidoniasts. Also,of interest are tall cylindrical bases of white marble, supporting gray columns in porticoes of the atrium - one of these saves unfinished embossed representations..

It owes its name to the famous statue of the sculptor Polykleitos.
