Sash windows are often thought to have come from Holland in the 17th century; however, the oldest surviving sash windows were actually seen here in England and date back to the 1670s. The stunning Ham House in Richmond-upon-Thames, which was originally built in 1610, is known for having one of the first examples of early sash windows. It is believed that the original creator was a man named Robert Hooke, but some still believe that they were Dutch.
