Historic Oregon City is the home of the third house ever built in the Oregon Territory, and Clackamas County's oldest house. The Ermatinger House was erected by one of Oregon's prominent citizens, Francis Ematinger, a Portuguese native who was schooled in England and was a former Hudson's Bay employee. Ermatinger arrived in Portland in 1825, made his mark in Oregon retail and government, and erected this house in 1847.
Some of the more significant landmarks include:
- Barclay House
- Holmes House / Rose Farm
- Mountain View Cemetery
