Aberdeen is also home to two artistic schools: Gray's School of Art, founded in 1886, which is one of the oldest established colleges of art in the UK. Scott Sutherland School of Architecture and Built Environment, was one of the first architectural schools to have its training courses recognised by the Royal Institute of British Architects. Both are now part of Robert Gordon University and are based at its Garthdee campus. North East Scotland College has several campuses in the city and offers a wide variety of part-time and full-time courses leading to several different qualifications in science. The Scottish Agricultural College is based just outside Aberdeen, on the Craibstone Estate. This is situated beside the roundabout for Aberdeen Airport on the A96. The college provides three services—Learning, Research and Consultancy. The college features many land based courses such as Agriculture, Countryside Management, Sustainable Environmental Management and Rural Business Management. There are a variety of courses from diplomas through to master's degrees. The Marine Laboratory Aberdeen, which specialises in fisheries, Macaulay Land Use Research Institute (soil science), and the Rowett Research Institute (animal nutrition) are some other higher education institutions.
