Castle Haven was a British soap opera centered around the residents of two Victorian seaside houses that had been converted into a series of flats and bedsits. It first aired on April 4, 1969, but was canceled just under a year later on March 26, 1970. 100 episodes were produced, but it is believed that only fifteen minutes of the series still exist; the rest were wiped after transmission, following the then-common practice of erasing videotapes.
