Belfast Metropolitan College (previously known as Belfast Institute of Further and Higher Education or BIFHE) is a further and higher education institution in Belfast, Northern Ireland. The college offers both vocational education and academic qualifications. With over 50,000 enrolments and an annual budget in the region of £45 million, it is Northern Ireland's largest college. The college encompasses a number of different campuses around the city. The largest are the Millfield Campus and College Square East building. College Square East is known colloquially as the 'Black Man Tech'. This is because of the statue of Dr Henry Cooke, a leading 19th century Presbyterian, which stands outside the building. The statue of Cooke is not marble, but copper, like most other architecture around the city of Belfast around the same time. Due to exposure to the elements, most of these statues and domes around the city have oxidised, producing a green colour of copper oxide, especially noticeable on the nearby City Hall building. The College Square East campus specialises in courses involving computing, technology and the three traditional sciences (Biology, Chemistry and Physics).
