Port Logan once a small fishing village, is now more famous for being the filming location for the BBC series "2000 acres of skye". In the series Portpatrick was meant to be part of the island of Skye in Scotland, where Port Logan (seen here) was meant to be a smaller island off the coast of Skye. The taller building at the end of the row of houses just at the stern of the yaught is the Port Logan Inn, which played a big part in the TV series.
