READING, Pa. -

It is official. Say so long to the Sovereign Center and the Sovereign Performing Arts Center in downtown Reading.

The names of the two entertainment venues were changed Thursday as part of Sovereign Bank's switch to the Santander name.

The Sovereign Center on Penn Street is now known as the Santander Arena; the Sovereign Performing Arts Center on North 6th Street is now known as the Santander Performing Arts Center.

The venues also have a new website.

Sovereign Bank, formerly based in Wyomissing and renamed Santander Bank on Thursday, has owned the venues' naming rights since they were first sold in 1999.
