Denver Botanic Gardens sits on the former Prospect Hill Cemetery, which was converted in 1907.
"Back during the 1800s this entire area between Cheeseman and Congress Parks was a cemetery," said Will Jones, a spokesperson for the Denver Botanic Gardens.
Back then it was called Mt. Prospect Cemetery. Legend has it as many as a few thousand human remains are still present underneath Cheeseman Park.
The discovery was made shortly before noon on Friday. Crews immediately called the Denver Coroner's office. Staff members at the gardens knew there was a possibility of bone discovery and had plans in place to contact the medical examiner if they were found.
If the remains are found to be human remains the bones will be taken to Mt. Olivet Cemetery. That is where thousands of human remains from Mt. Prospect Cemetery were taken around 1900 and 1950.
The parking structure is going to be two stories deep, and historians told them they might find something underneath all of the dirt.
The three-level parking garage will double the number of parking spaces available at the Botanic Gardens./>
