 The Green Island lighthouse at the entrance to Catalina harbor was the first lighthouse designed and commissioned by Robert Oke in 1855, after he accepted the appointment as Chief Inspector Newfoundland Lighthouse Service.Oke's designs, with integrated keeper's dwellings, are notable for being well-proportioned and for classic detailing, including strong cornices, pilasters and wide mouldings.The Cape St. Mary's Light Tower was originally built by Oke as a brick shaft between 1859 and 1860 and today the tower is a Recognized Federal Heritage Building.
