The Hagen History Center is celebrating Victorian Holidays at the mansion.
The Watson-Curtze Mansion has been decorated for the season on all three floors.
A team of volunteers, led by the owner of Copper Carriage, put up more than 30 trees to get visitors in the spirit.
The history center is also beginning the season with two new exhibits called "Made You Look" and "100 Years of the Erie Zoo."
The organization is offering half-priced admission for this weekend only thanks to their sponsor Erie Federal Credit Union.
"Normal times, it's magnificent. It really shines for Christmas so I think everyone will really appreciate it. It will truly get you into the holiday spirit and you want to come and see it," said Geri Cicchetti, advancement director at the Hagan History Center.
