Pembroke is a city in Renfrew County, Ontario, Canada, at the confluence of the Muskrat River and the Ottawa River in the Ottawa Valley. Pembroke is the location of the administrative headquarters of Renfrew County, though the city itself is politically independent. It is one-hundred fifty kilometres northwest of Ottawa.HistoryThe first European settler to the area now known as Pembroke was Daniel Fraser in 1823, who squatted on land that was discovered to have been granted to a man named Abel Ward. Ward later sold the land (where Moncion's Grocers is located) to Fraser, and nearby Fraser Street is named after the family. Peter White, a veteran of the Royal Navy arrived in 1828, squatting beside Fraser on the land where Dairy Queen is now located. Other settlers followed, attracted by the growing lumbering operations of the area.Originally named Miramichi, Pembroke became a police village in 1856. Pembroke is indirectly named after Sidney Herbert, First Admiralty Secretary from 1841 to 1845 and son of George Herbert, 11th Earl of Pembroke.Pembroke was incorporated as a town in 1878 and as a city in 1971. It was named seat for Renfrew County in 1861. This set the stage for construction shortly thereafter on the Renfrew County Courthouse, which was finished in 1867, and the arrival of many civil servants, much wealth and much construction. In the 20-year period following 1861, Pembroke basically became the city it is today in terms of layout and buildings, although many homes and other structures have been lost to time. A fire in 1918 destroyed much of Pembroke's downtown.
