LOUISVILLE, Ky. (WDRB) -- A Frankfort Avenue landmark has reopened.

Louisville Water Company showed off its fully restored historic Crescent Hill Gatehouse on Tuesday.

Work began in 2013. The building's slate roof was completely replaced and the 3,000 tiles in the terra cotta ceiling were cleaned and restored. The limestone steps leading up to the gatehouse and reservoir were also cleaned and repaired.

"This is still an operating facility for the Louisville Water Company," said Jim Brammell, Louisville Water Company president and CEO. "It has been since 1879. Outside in the reservoir, on either side of the building is 110 million gallons of water, raw water, from the Ohio River, just waiting to be purified and sent out to the taps."

The three-story Gothic structure was designed to resemble a castle along the Rhine River in Germany.

The gatehouse was designated a Kentucky Historic Site in 2010.
