Allen Centennial Gardens, Public garden at University of Wisconsin-Madison, United States.

Allen Centennial Gardens is a public park at the University of Wisconsin-Madison featuring themed garden sections with diverse plant collections. Across two acres, walking paths connect seasonal displays and a historic house built in 1896 with Queen Anne architectural details.

The property was created after the destruction of teaching gardens in 1979 as a new space to celebrate the agricultural college's hundredth anniversary. The listed house was built in 1896 and served as the residence for four heads of the agricultural sciences department.

The space serves students as a learning environment where they gain hands-on knowledge about plants and sustainable practices. Visitors can observe how the gardens function as an active teaching and research center for the university community.

The grounds are free and open year-round with clearly marked walking paths throughout. Plan your visit with comfortable walking shoes as the terrain can become muddy during wet weather.

The garden opened in October 1989 thanks to a gift from Ethel Allen, widow of bacteriologist Oscar Allen; its name honours him and the College of Agricultural and Life Sciences' 100th anniversary. The 1896 Queen Anne house on the grounds, designed by Allan D. Conover and Lew F. Porter, has had its interior stripped and awaits renovation.
