Fitzwilliam Square is the smallest and the last of Dublin's five great Georgian squares, completed in the 1830s and the only one whose central garden remains private (accessible only to residents). The square is architecturally the most uniform of Dublin's Georgian set pieces, with the brick facades and fanlights intact on all four sides.
The surrounding streets — Fitzwilliam Street Lower and Baggot Street — are among the best places in Dublin to walk and appreciate Georgian architecture. The famous long Georgian terrace on Fitzwilliam Street stretching toward Merrion Square is one of Europe's longest unbroken Georgian streetscapes.
