Logo design for a nonprofit organization

Hello! My organization needs a logo. We maintain a local museum, which has been closed for over two years. Now that it has reopened, we decided that we needed a refresh for our logo. Here is a link to our site: http://www.champaignmuseum.org/

For the logo design, anything will do! We'd like to request that the logo is more on the formal/professional side. Thanks to anyone who gives it a shot!
