Ponta Delgada, the capital of an administrative district, comprising the islands of St Michael's and St Mary in the Portuguese archipelago of the Azores. Pop. (1900), 17,620. Ponta Delgada is built on the south coast of St Michael's, in 37° 40' N. and 25° 36' W. Its mild climate, and the fine scenery of its mountain background, render it very attractive to visitors; it is the commercial centre, and the most populous city of the archipelago. Besides the cathedral, it contains several interesting churches and monasteries, and an observatory. Formerly its natural inner harbour only admitted vessels of light draught, while larger ships were compelled to anchor in an open roadstead, which was inaccessible during the prevalence of southerly gales. But great improvements were effected after 1860 by the construction of a breakwater 2800 ft. long.
