Vale of Avoca. Co. Wicklow, Ireland, 1890's

The Vale of Avoca is the name of a deep ravine and of a large viaduct which carries St. Clair Avenue over the ravine, both within the city of Toronto. When built in the early 1920s, the triple arch bridge served to connect the well-established community of Deer Park with the developing community of Moore Park; it replaced an older structure and straightened the alignment of St. Clair Avenue in the process. The bridge and ravine are named after a poem by Thomas Moore.

Avoca (Irish: Abhóca, formerly Abhainn Mhór, meaning "the great river") is a small town near Arklow, in County Wicklow, Ireland. It is situated on the River Avoca.

The Avoca area has been associated with its famous copper mines for many years and the valley has been immortalised by Thomas Moore in the famous song The Meeting of the Waters. The name of the song derives from the meeting of the Avonmore and Avonbeg rivers, about two miles from the village of Avoca. The song is said to have been written under a tree, the stump of which remains by the Meetings.

Avoca was once known as Newbridge. It subsequently became known as Ovoca, and then in Victorian times as Avoca. Ptolemy mentions the river Obhoca on his early map of Ireland. The official name of the village is now Avoca in English and Abhóca in Irish. None of the other names are used today.
