The adjacent Veterans Memorial Coliseum and Knights of Columbus tower were conceived as a sculptural ensemble of monumental scale, to be viewed from moving vehicles on the multi-lane access road known as the Oak Street Connector (CT Route 34) . The site comprises three parcels totalling 2.34 acres.  \n• Other notable features of building or site (Interior and/or Exterior)  \nThe structure consists of four cylindrical reinforced concrete towers clad in dark brown structural clay tile with a central concrete elevator core. These elements are linked by steel floor structures. The lobby and mezzanine levels are set back and clad in reflective glazing. The 20 upper floors have 90-foot long girders of exposed weathering steel connecting the corner cylinders. Steel framing supports the floors within this perimeter, with the glazing set back five feet behind the primary girders. All four sides are identical. The floors contain primarily open-plan office space while exit stairs and support services including rest rooms are in the corner cylinders.  \nMature groves of honey locust trees flank the tower to the north (the paved Columbus Park, currently closed) and to the southeast (lawn, trees, and signage ) .
