In the Milwaukee suburb of Wauwatosa, there is an area that is commonly referred to as the “county grounds.”
It is a vast area of land, parts of which is leased to Children’s Hospital of Wisconsin and Froedtert Hospital (which was once the county-owned Doyne’s Hospital until sold off decades ago). The county grounds also is home to the Milwaukee County Behavioral Health Division, the delapidated county greenhouses, and a business park.
The county grounds also contains two rare treasures – the Monarch Trail and the Eschweiler Buildings.
The Monarch Trail is part of the last undeveloped and ungroomed natural space in Milwaukee County. It contains one of the rare places in the country which acts as an oasis for the Monarch Butterflies. Due to the unique form of the county grounds – including a large sequoia tree – and an abundance of milkweed, the Monarch butterflies’ food, the area is a spot where the Monarchs gather every year in their annual migration from the north to their wintering homes in Mexico and Central America.
