When BP purchased Chicago-based Amoco in 1998, the company said it would move its headquarters from Cleveland to Chicago. The building was purchased by the Chicago-based EQ Office in 1996 for $144 million, which in turn sold it to Harbor Group International in June 2005 for $141.25 million. Harbor Group worked with Electra Real Estate (TASE: ELTR) to purchase the building. The building was subsequently renamed 200 Public Square. Most Clevelanders and the Harbor Group still recognize it as the BP Tower, although many still refer to it as the Sohio Building.
