Pella Historical Museums will close for the season following regular hours on Saturday. Director Jessi Galligan says she’s thankful for their many volunteers and donors who supported the non-profit organization dedicated to protecting the city’s rich history. Galligan says those looking to make an end-of-year donation can consider membership or a donation to keep those efforts going. Additionally, Galligan says they are also looking for volunteers to support the upcoming 90th Tulip Time celebration in early May. Find out more about both options at the Pella Historical website.
