The Clock House in Baltimore, Maryland

This Victorian rowhome on the corner of 21st and St. Paul features three large mechanical clocks, wound by hand by its resident. Most unusually, a wrought-iron and copper dragon sits below one of the clocks, striking the hour with its tail on a bell hanging from its mouth.The home is said to contain a collection of antique clocks, fans, organs, and mechanical music devices curated by restoration expert Durward Center. Mr. Center has restored notable instruments, including the organ at Oakley Court in the UK—made famous by the Dracula movies and the Rocky Horror Picture Show.
