The Forest Grove Sound was an unexplained noise, described by The Oregonian as a "mechanical scream", heard in Forest Grove, Oregon in February 2016. In February 2016, a high-pitched noise was heard intermittently at night in Forest Grove, Oregon. The Department of Forestry determined that their equipment was not the cause of the sound. The news about the noise was first shared with Dave Nemeyer by a Forest Grove resident, who posted a video of it on the city's Facebook page. The Washington Post described the noise as sounding like a "giant flute played off pitch", car brakes, or a steam whistle. NBC News described it as "akin to a bad one-note violin solo broadcast over a microphone with nonstop feedback". It reportedly lasted from ten seconds to several minutes at a time. The fire department of Forest Grove did not consider the sound to be a safety risk. The noise occurred near Gales Creek Road. Neither the City of Forest Grove Public Works Department nor the Fire Department were able to explain the noise. According to NW Natural, there were no problems with gas lines in Forest Grove at the time. In February 2016, Andrew Dawes, a professor of physics at Pacific University, mapped the locations where the noise had been heard, although the results were inconclusive and did not suggest any single location.Throughout February 2016, approximately 200 calls were made to the Forest Grove Police Department, according to Captain Mike Herb, who said that most of the calls were suggesting explanations for the sound, ranging from frogs to aliens to Bigfoot. In late-February 2016, the Forest Grove police department announced via Facebook that the noise did not pose a safety hazard, and the police announced they were halting their investigation until further information appeared. However, after February 2016, the noise was not heard. The final point was plotted on Dawes' map on February 27, 2016, and the police and fire departments closed the case. Dave Nemeyer, the Forest Grove Fire Marshal, suspected the noise to be "a faulty attic fan or heat pump."In October 2016 Theatre in the Grove, a performing arts theatre in Forest Grove, created a haunted house based on the Forest Grove noise called "Aliens in the Grove".

C. W. Mertz Rental House No. 2 is a building in Forest Grove, Oregon that was listed on the National Register of Historic Places on June 21, 2005. It was built by architect John Taylor. It is a contributing property within the Clark Historic District.The house is notable for being built of hollow concrete walls, a process developed by John Taylor. The Taylor Process Hollow Concrete Wall system had two concrete walls with a continuous air space between them. Taylor filed a patent for the mold that was used to build the walls. As the walls were built up vertically from a concrete foundation, reinforcing ties were added between the double walls. When the specified height was reached, the top was closed with a suitable cap. The exterior walls could be finished with any adaptable finish, but stucco was the most common method. The Zula Linklater House in Hillsboro was also built using this construction method. About a dozen buildings in Forest Grove, and a few outside the city, were constructed using Taylor's double-wall method.: 9–11 

The Stephen and Parthena M. Blank House, also known as the Old Stagecoach Stop, is a historic residence located in Forest Grove, Oregon, United States. Built in 1858 or 1859, it is one of Forest Grove's distinctive examples of mid-19th century Greek Revival architecture. Gradual extensions of the structure from the 1850s to the 1880s employed multiple frame construction methods; the house particularly exhibits clear remnants of the balloon-frame and box-frame techniques of the period. Oral tradition suggests that the house was also used as an overnight stagecoach inn on the route between Portland and Tillamook in the late 19th or early 20th century. It was listed on the National Register of Historic Places in 1988.
