Telephone junction box located outside the southern entrance to Bangor Post Office at the corner of Main Street and Castle Park Avenue. These boxes, first used by the General Post Office Telegraph Department (this one is marked GPO - see J5081 : Telephone junction box, Bangor) and later by British Telecom, are still commonly found in the UK. Most are painted in this colour - known as GPO green - but some are also found in gray (there are examples in central Belfast). Recently some of these boxes in Bangor have been removed as part of the "BT Infinity" project which aims to increase broadband speeds in the area - new cables have been installed which presumably do not fit in the old boxes and larger modern replacements have been sited in their place.
