I fell in love with this mysterious structure the first time I saw it! In the late 19th century, it housed large wheels that helped channel water from the Lake Montebello reservoir to the surrounding city of Baltimore. Today, it is risks getting torn down and [efforts to preserve the building are ongoing](https://www.preservationmaryland.org/valve-house/). "The Lake Clifton Valve House, or Gate House, is a massive octagonal stone structure. Large Romanesque archways alternate with Gothic style windows which once contained stained glass. Remnants of the colorful glass patterns may still be seen in the turret, atop an intricate tile roof supported by a complicated system of iron trusses." -[Maryland Historical Trust](https://mht.maryland.gov/nr/NRDetail.aspx?NRID=50) Created in RealityCapture from 618 images taken with a drone.
