  • The Straus Building was the first building in Chicago with 30 or more floors.
  • The building was originally named after S.W. Straus & Co., a dealer of investment bonds and one of the leading financers of major real estate in Chicago during the late 19th and early 20th century.
  • A blank limestone plaque tops the center of the east base at the 4th floor level. It used to appear one floor higher with the inscription "S.W. Straus & Co."
  • The previous Straus Building was a 10-story structure at the northwest corner of Clark and Madison Streets. It was demolished in 1941.
  • For several years the building was occupied by Continental National Insurance, the predecessor to CNA, which built the CNA Plaza complex as a western extension of this building.
  • CNA Plaza North was the first of CNA's extensions to the west, with contiguous floor connections between the two structures.
  • Referred to as Britannica Centre since 1980, the building was converted into 220 luxury condominium units and renamed Metropolitan Tower on the Park.
  • An open light court rises above the banking hall, directly behind the tower.
  • The 20- foot glass beehive ornament at the peak of the ziggurat holds a deep blue light, a prominent feature of Grant Park's night skyline. It is supported by four stone bisons, which symbolize industriousness, thrift, and strength.
  • The beehive originally held four searchlights which shone in the four cardinal directions.
  • The tower contains four bells just beneath the beehive which chime G.F. Handel's "Cambridge Quarters" on the quarter-hours.
  • The carillon bells were unused for many years until they were restored in 1979 by then-owner Dino D'Angelo for the Chicago visit of Pope John Paul II.
  • The original main entrance was a pair of elaborately carved bronze doors set in a marble portal flanked by bas-reliefs.
  • The lobby is L-shaped, connecting the east entrance on Michigan Avenue with Jackson Boulevard on the north.
  • A spacious banking hall laid out like a basilica occupied the second floor, with a 45 foot high coffered ceiling and 16 Corinthian columns.
  • At the west end of the banking hall there was a large Florentine-style stained glass window depicting a 16th century full-rigged ship under allegorical figures of art and justice.
  • The side arcades of the banking hall were decorated with gold medallions.
  • The main entrance used to be in the center of the east side, through the largest of the archways, leading directly up to the banking hall by a grand staircase.
  • The base has been altered from its original design, with rectangular window openings replacing the giant arches on Michigan Avenue and Jackson Boulevard.
