Officials in Bethlehem are inviting you to take a step back in time.

ArtsQuest is teaming up with the Historic Bethlehem Museum and Sites organization to offer a new art and architecture tour at the SteelStacks.

The 75-minute tours focus on how the architecture of the steel mills evolved over time.

Participants will get the chance to check out buildings that date back to the 1860s.

"People are fascinated with the scale and the design. These are huge buildings and it's not often that you can get up close and personal with buildings of this size that were used for industry," said Charlene Donchez Mowers, Historic Bethlehem Museum and Sites.

The art and architecture tours will be held Fridays through Sundays at 11 a.m. Tickets are $12.
