Celebrate the Occasion That You Deserve It is believed that "Munnysunk," the former estate house of Frank Bailey, was initially constructed somewhere in the 1800s. After purchasing the property, Frank enlisted the help of Craig Severance to renovate it while preserving the rustic charm of the neocolonial structure. Bailey House and its surrounding grounds, which can accommodate up to 75 guests for wedding ceremonies, wedding receptions, and private events, has been transformed into a stunning venue.
