The Hazelwood Historic House Museum sits on its original site overlooking the Fox River. The house is a restored 1837 authentically-furnished, Greek-revival home. The Hazelwood grounds include several garden areas overlooking the Fox River. The Meredith B. Rose and John M. Rose Educational Annex was constructed in 2001 and sits directly behind the museum. Hazelwood also houses the offices of the Brown County Historical Society.
