O'Connell Street (Irish: Sráid Uí Chonaill) is Dublin's main thoroughfare. It measures 49 m (54 yds) in width at its southern end, 46 m (50 yds) at the north, and is 500 m (547 yds) in length. During the 17th century, it was a narrow street known as Drogheda Street (named after Henry Moore, Earl of Drogheda). It was widened in the late 1700s and renamed Sackville Street (Sráid Saicfil, named after Lionel Sackville, 1st Duke of Dorset) until 1924, when it was renamed in honour of Daniel O'Connell, a nationalist leader of the early 19th century, whose statue stands at the lower end of the street, facing O'Connell Bridge. Located in the heart of Dublin city, it forms part of a grand thoroughfare created in the 18th century that runs through the centre of the capital, terminating at City Hall and Dublin Castle. Situated just north of the River Liffey, the street runs close to a north-south orientation. It has often been centre-stage in Irish history, attracting the city's most prominent monuments and public art through the centuries, and formed the backdrop to one of the 1913 Dublin Lockout gatherings, the 1916 Easter Rising, the Irish Civil War of 1922, the destruction of the Nelson Pillar in 1966, and many public celebrations, protests and demonstrations through the years – a role it continues to play to this day. State funeral corteges have often passed the GPO on their way to Glasnevin Cemetery, while today the street is used as the main route of the annual St. Patrick's Day Parade, and as the setting for the 1916 Commemoration every Easter Sunday. It also serves as a major bus route artery through the city centre. The modern tram, the Luas, has undergone an extension and trams now run once again through O'Connell Street. It only travels in one direction, the return loop, to link the system at St. Stephen's Green, runs via Marlborough Street, parallel with and east of O'Connell Street.
