A grandfather clock is a tall, freestanding clock that typically features a pendulum and weights. These clocks are known for their distinctive design, often made of wood, and can be quite ornate. They usually stand over six feet tall and are designed to be a centerpiece in a room. The name "grandfather clock" originated from a popular song in the 1870s. These clocks are not only functional timepieces but also cherished heirlooms, often passed down through generations. They require regular winding to keep accurate time and are celebrated for their craftsmanship and historical significance.
