Named for the family of settler Joseph Titus, who established two sawmills and a fishery here in the 1700's, Titusville became a major industrial and transportation center in the mid-19th century. Spurred by the construction of the Delaware and Raritan Feeder Canal in 1832 and the Belvidere Delaware Railroad in 1852, Titusville by the mid-1800s had thriving mills, stores, shops and a population of 300. Its abundance of housing stock, including fine examples of Greek Revival, Second Empire and Italianate architectural styles, helped it gain a place on the National Register of Historic Places in 1983.
