Officials from the Baltimore Police Department, the Baltimore city government, and the B&O Railroad Museum held a ceremonial groundbreaking on Tuesday to mark the construction of a new stable facility for the department's mounted unit.

The unit has operated out of a former car dealership downtown since the 1970s, but a yearlong fundraising drive has raised about $1.3 million for a new facility on the railroad museum 40-acre property in Southwest Baltimore, according to the Baltimore Sun.

Construction on the 13,000-square-foot facility is expected to begin by mid-November, and take roughly six to eight months.

The Baltimore Police Department mounted unit—in its 130th year—is considered to be the country’s oldest continuously operating mounted police unit.
