Mitchell Park Horticultural Conservatory (The Domes) | Milwaukee

The Mitchell Park Horticultural Conservatory, widely known as The Domes, is an iconic botanical conservatory located in Mitchell Park on Milwaukee’s south side. It is celebrated not only for its diverse and vibrant plant collections but also for its pioneering architectural design. The Domes have become a beloved landmark in Milwaukee and a unique horticultural destination in the Midwest.

History and Architectural Significance

The history of The Domes dates back to the late 19th century. Milwaukee’s original conservatory was built in 1898, designed by architect Henry C. Koch, and inspired by London’s Crystal Palace, featuring an elaborate glass structure. However, by the mid-20th century, the aging conservatory had deteriorated beyond repair and was demolished in 1955.

A design competition was held to create a modern replacement. Local architect Donald L. Grieb won with an innovative concept for three interconnected conoidal domes. Construction began in 1959 and was completed in 1967. The domes are considered architectural marvels, recognized as the world’s first conoidal domes. Each dome measures approximately 140 feet in diameter and rises 85 feet tall. Their structure consists of a steel-reinforced concrete frame, covered with aluminum and wire-reinforced plate glass, creating an impressive and futuristic appearance that still stands out today.

The Three Domes and Their Unique Environments

The Mitchell Park Conservatory is comprised of three distinct domes, each designed to simulate different climatic and ecological regions, offering visitors a rich and immersive botanical experience.

Floral Show Dome
This dome serves as the conservatory’s exhibition space for vibrant seasonal flower displays. It hosts five major floral shows each year, transforming the space with themes that correspond to spring, summer, fall, and winter. The most popular event is the annual Train Show, which features detailed model trains weaving through miniature landscapes adorned with thousands of live plants. This dome’s constantly changing displays provide a fresh experience for repeat visitors and showcase the creativity and horticultural expertise of the conservatory’s staff.

Tropical Dome
The Tropical Dome replicates the lush environment of a tropical rainforest. It houses nearly 1,000 species of plants native to warm, humid climates, including cacao trees, banana plants, papaya, guava, orchids, and ferns. The environment is carefully maintained with high humidity and temperatures that mimic the tropics, creating a vivid and educational experience about rainforest biodiversity. In addition to plants, the dome is home to various birds and small wildlife, enhancing the immersive ecosystem feel.

Desert Dome
The Desert Dome presents the unique flora of arid regions from Africa and the Americas. It features a wide variety of cacti, succulents, and drought-resistant plants. The exhibit educates visitors about desert ecosystems and adaptations plants have developed to survive in harsh, dry climates. Rock formations and sand landscapes complement the plants, offering a realistic desert setting.

Outdoor Gardens and Additional Attractions

Surrounding the domes, visitors can explore beautifully landscaped outdoor gardens that support local ecology and pollinators. Notable among these is the Monarch Butterfly Waystation Garden, which contains milkweed and other native plants essential for monarch butterflies’ life cycles.

The Education Center offers interactive exhibits geared towards children and families. It includes features such as a reading nook, a small treehouse, and forest-themed learning activities, providing a hands-on, engaging environment to connect with nature and horticulture.

Preservation, Renovations, and Future Outlook

The Domes have required ongoing maintenance and renovations over the decades due to their age and unique structure. Challenges such as cracked glass panels and wear on the steel framing have led to periodic repairs. In 2016, the conservatory was temporarily closed to address urgent structural issues, including replacing cracked glass and improving lighting systems.

Despite these efforts, concerns about long-term preservation remain, and there have been discussions about the future of the facility. Nonetheless, The Domes continue to operate as a treasured Milwaukee institution, attracting locals and tourists alike.
