Mountjoy Square is a Georgian garden square on the northside of Dublin in the Dublin 1 postcode district. Located just under a kilometre from the River Liffey, it is one of five Georgian squares in Dublin. Each side of the square is exactly 140 metres in length and many famous people have resided there including Arthur Guinness, Sean O'Casey and more. The School of Art Design and Printing and the Department of Social Sciences of Dublin Institute of Technology are based on the square while the park has playing areas for football, basketball and table tennis as well as a playground for children. Close to the centre of Dublin city and having the major artery Gardiner Street as its West side, Mountjoy Square has considerable transport links in its immediate locality. The Dublin Bus termini for the 7, 7b, 7d, 8 and 46e are on the North side of the square and run toward the south east of the city. Routes 33, 41, 41b and 41c stop on the West side of the square on their way to the northern suburbs. The square is also stop covered by the hop-on, hop-off city centre 50 cent fare. The 41 bus is almost certainly the cheapest transport link to Dublin Airport from the city at €1.80 (in 2010) from the square. The main entrance to Dublin Bus' Summerhill Depot is on Mountjoy Place, just off the south-east corner of the square. In 2009, the Dublin Bikes bicycle sharing system was launched and has one of its more northerly stations on the west side of Mountjoy Square, providing easy access for commuters, locals, and tourists. In 2013 a similar pay-as-you-go car hire scheme stationed a car on the square. The ""Go-Car"" is parked on Mountjoy Square West.
