TULSA, Okla. —
The 5.6 magnitude earthquake that struck Oklahoma in November 2011 has forced the closing of a historic building in downtown Tulsa owned by Tulsa World publisher World Publishing Co.
The Excalibur Building — also known as the Main Mall Building — was closed this week after an engineer determined the earthquake caused structural damage that makes the building unsafe. The engineer says another earthquake could cause the building to fall into the adjacent Tulsa World Building or into the street.
The building was constructed between 1913 and 1917 and was originally known as the Palace Building. It housed Palace Clothiers until the company went out of business in the 1960s.
It was purchased in 1997 by World Publishing as part of a Tulsa World (http://bit.ly/Uvq8RX ) expansion project.
