Wardenclyffe Tower (1901–1917), also known as the Tesla Tower, was an early experimental wireless transmission station designed and built by Nikola Tesla on Long Island in 1901–1902, located in the village of Shoreham, New York. Tesla intended to transmit messages, telephony, and even facsimile images across the Atlantic Ocean to England and to ships at sea based on his theories of using the Earth to conduct the signals. His decision to increase the scale of the facility and implement his ideas of wireless power transmission to better compete with Guglielmo Marconi's radio-based telegraph system was met with refusal to fund the changes by the project's primary backer, financier J. P. Morgan. Additional investment could not be found, and the project was abandoned in 1906, never to become operational.

The current stainless steel water tank holds 50,000 gallons and replaced the original wooden tank in 1984. The site has two other structures, an old power plant building and a 100,000 US gallon reservoir. The Lena Electric Plant Building was constructed in 1905 and the reservoir completed in 1907. The Lena Water Tower was listed on the U.S. National Register of Historic Places in 1997; the reservoir was included as a contributing property to the listing.

The Central Steam Heat Plant, commonly known as Steam Plant Square, or simply as the Steam Plant, is a historic building in Downtown, Spokane, Washington. Originally built to provide steam heating to more than 300 buildings in Spokane's city center, the Steam Plant served that purpose until the 1980s, when it was no longer viable. In the 1990s, the Steam Plant and adjacent Seehorn-Lang Building were converted into Steam Plant Square, a commercial, retail and restaurant center. The conversion maintained many of the industrial steam plant structures such as furnaces, boilers, catwalks and pipe networks, which can still be seen and explored by visitors and patrons. The Steam Plant's pair of 225 foot tall stacks have been a unique and iconic aspect of the city's skyline for more than a century, and are illuminated from their base at night. If the stacks were considered to be a building, they would rank as the third tallest in the city.
