The bee is a common symbol around Manchester
Most road barriers are black with a gold bee engraved. It is a common symbol around the town hall, and above many doors of traditional buildings or work places. It symbolises hard work and dedication, and is derived from St Bede, a hard working intelectual who dedicated his life to education and teaching to others. There is a school named after him in Manchester, St Bede's College, which also has the symbol of the bee on the badge.
St Bede was burried in Durham Cathedral and his resting place can now be visited, a tomb in the cathedral itself.
