Some of the earliest houses still survive on the south and north sides of the Green. These are identifiable by their lower height and narrow fronts, illustrating how plots were subdivided. Later buildings on the east side show a dramatic change in scale, with much larger and grander houses, many by
Gustavus Hume.
Iveagh House on the south side was created from the joining of two earlier houses (numbers 80 and 81) by
Benjamin Guinness in the 1860s. It was donated to the Irish State by the Guinness family in 1939, and now houses the main offices of the
Department of Foreign Affairs and Trade. Also on the south side of St Stephen's Green are
Newman House (numbers 85 and 86, after
John Henry Newman) and
University Church. These are home to the Catholic University of Ireland, which was founded in the 19th century. It is linked with
University College Dublin, but is no longer active educationally in its own right. The
Unitarian Church, Dublin, built in the
Gothic Revival style, is located on the West side of St Stephen's Green. Also on the west side is the
Royal College of Surgeons in Ireland (number 123), home to the oldest of the Republic of Ireland's six medical schools. On the west side, at the top of
Grafton Street, is the
Stephen's Green Shopping Centre, built in October 1988. It was, at the time, Ireland's largest shopping centre. Its style was intended to represent a conservatory on the side facing the Green and to mirror the brickwork design of the opposing
Gaiety Theatre on South King Street. On the north side of St Stephen's Green, there were four houses which are now two clubs (originally
gentlemen's clubs): the
Hibernian United Services Club (number 8, closed in 2002), the ''Stephen's Green Hibernian Club'' (number 9, originally the Stephen's Green Club, prior to its merger with the Hibernian United Services Club), the "Friendly Brothers of St Patrick" (number 22, now closed) and the
Kildare Street and University Club (number 17). This side of the Green also has the historic
Shelbourne Hotel, Dublin's only surviving Victorian hotel. The
Little Museum of Dublin, which is housed in a restored Georgian townhouse can be found in number 15. Also on the north side, Heritage House at 23 St Stephen's Green, was the location of a tearoom which hosted the first public
Alcoholics Anonymous meeting in Ireland, on 25 November 1946. ''Loreto College, St Stephen's Green'', one of Ireland's best-known fee-paying schools for girls, is located at number 53, on the East side of the Green. ''St Vincent's Hospital'', now located in a suburb on the south side of Dublin, was formerly located in buildings on the East side of St Stephen's Green and on Leeson Street. It is now the headquarters of bank
PTSB. During the mid 20th century, a number of the Georgian buildings on the Green were demolished in favour of modern office blocks. Most of the east side of the square is modern reproduction terraces in front of offices. Among the buildings that were lost was No. 21, the former St Andrew's College, which was demolished by
Irish Life in February 1969 and a new office block, Stephen Court, designed by
Andrew Devane was constructed in its place. This building is deemed one of the more successful modern interventions on the Green. ==Transport==
