The Observatory Municipal Heritage Building

1 Bonaventure Avenue, The Observatory, is designated a municipal heritage building because it has historic and aesthetic values.

1 Bonaventure Avenue is historically valuable because of its age and association with first owner, John Delaney. Irish-born Delaney (1811-1883) was the owner of the Observatory from the time of its construction until his death. He came to Newfoundland and represented Placentia in the House of Assembly 1848-52 and 1855-56. He was appointed Postmaster General in 1860 and oversaw improvements in the mail service. His interest in meteorology led, in effect, to the development of a local meteorological service under the aegis of the Meteorological Service of Canada. A regular informant of the Smithsonian Institute in Washington, he was made a Fellow of the Royal Meteorological Society in 1873. He is also significant for having made and operated the first telephone in Newfoundland in 1878. Delaney’s historical significance rests on his work in meteorology and on the telephone. 1 Bonaventure Avenue was equipped with an observatory when it was constructed. It was a two-storey structure attached to the rear addition but has since been demolished. It was from this structure, and the attached house that Delaney studied meteorology as a Fellow of the Royal Meteorological Society and thus made a significant contribution to the society.

1 Bonaventure Avenue is aesthetically valuable because it is a beautiful example of Second Empire Design, having survived the Great Fire of 1892. This wooden, two-storey house has a Mansard roof with a projecting central tower, itself with a mansard roof. The Observatory has returned, moulded eaves and arched one over one windows. Above the main façade windows are moulded brackets supporting wide shelves, and this is reflected around the front door. This house stands alone in its decoration, as it is the only single dwelling in the immediate area.
