Toledo Botanic Garden has closed its doors for a one-week trip to Colorado after a few visitors died.

The Botanic Gardens on the outskirts of downtown Toledo on Monday closed its gates to its visitors after two visitors died after falling into a well in the fall of 2016, officials said.

They said they are continuing to investigate.

The Toledo Botanical Gardens is one of the few botanic parks in Ohio that is open during the summer and winter months.

Toledo Botanic Park, which was established in 1854, is one in a growing number of botanic attractions across the country that is closing for a week to accommodate seasonal closures, including at some schools and colleges.

The Toledo Botanics was among the few parks in the state with its own security detail to keep visitors safe from criminals and natural disasters.

The park has been a popular destination for visitors since it opened in 1894.

Torton, Ohio, is about 30 miles (50 kilometers) south of Columbus.
