Bears at Riverside Park in Indianapolis? Not for the last century. But for nearly two decades beginning in 1899, a bear pit was among the most popular attractions at the park near the White River.

Consisting of a fenced, circular pen with two arched doorways that allowed the bears to enter a sheltered den, the bear pit at Riverside was featured on thousands of postcards that have become collectibles.

And the Riverside bear pit, although the longest-lasting and most significant local animal attraction during the era (it even sometimes was casually referred to as a "zoo"), wasn't the only collection of wildlife on display in Indianapolis parks.
