Aalborgtårnet: Aalborgtårnet (Aalborg Tower) is a 54.9 metre tall observation tower built of lattice steel in Aalborg, Denmark.  The tower is built on a hill, providing a total height of 105 metres above sea level.  The tower has a restaurant on the top.  The tower was completed in 1933, and underwent a major reconstruction from February 2005 to March 2005, in which the whole tower was pulled down and later reerected.

Jakobsberg Telecommunication Tower: Jakobsberg Telecommunication Tower is a 142 metre tall TV tower built of reinforced concrete on the 238 metre high elevated Jakobsberg near Porta Westfalica.  Jakobsberg Telecommunication Tower was built May 1, 1974 and September 28, 1978 as replacement for a small telecommunication tower also equipped with an observation deck, which was built in 1952 on the site

High Rock Tower Reservation: The High Rock Tower Reservation (or High Rock Tower Park) is a city park of Lynn, Massachusetts.  The roughly 4.5 acre park encompasses the summit area of a hill with commanding views of the surrounding area, as well as the Atlantic Ocean which is only a half a mile away.  The park's principal attraction is the High Rock Tower, a stone structure measuring 85 feet high, built in 1905, replacing an earlier tower built by Jesse Hutchinson of the Hutchinson Family Singers, a politically-active abolitionist singing group that performed throughout the northern United States from the 1840s to about 1880.  The Jesse Hutchinson acquired the property from the Pawtucket natives, and by 1846 built two Gothic Revival cottages (known as High Rock Cottage and Daisy Cottage) and later other cottages as well as the first tower which burnt down during a celebration of the Civil War's end.  http://myweb.northshore.edu/users/ccarlsen/poetry/lynn/highrockhistory.html

Diamondback (roller coaster): Diamondback is a steel roller coaster designed by Bolliger & Mabillard at Kings Island in Mason, Ohio, United States.  The ride is located in Rivertown just behind International Street and the Eiffel Tower.  When built in 2009, it was the first hypercoaster to feature a splashdown and the first Bolliger & Mabillard roller coaster at Kings Island.  Diamondback was previously the biggest investment in Kings Island’s history at $22 million (ahead of The Crypt and Son of Beast, each of which cost $20 million) until surpassed in 2014 by Banshee, an investment of $24 million.  The coaster has a 230 ft lift hill with a 215 ft-drop, featuring 10 total drops and a top speed of about 80 mi/h .  It is similar to Behemoth at Canada's Wonderland in statistics, layout, and seating.

Vitosha Mountain TV Tower: Vitosha Mountain TV Tower, better known as Kopitoto (Bulgarian: Копитото , "The Hoof") after the rock outcrop (1,348 m) it stands on, is a 186 meter tall TV tower built of reinforced concrete on Vitosha Mountain near Sofia, Bulgaria.  The footprint of the tower has the shape of a hexagon with three of the sides extended (i.e. almost triangular).  From the tower there is a commanding view of Sofia, and the tower can be seen from everywhere in Sofia, making it a landmark of Sofia's skyline.  It is the second tallest television tower in Bulgaria.

Cape Charles Light: The current Cape Charles Light is an octagonal cast iron skeleton tower lighthouse at the mouth of the Chesapeake Bay on Smith Island.  It is the tallest lighthouse in Virginia and the second tallest in the United States.  This particular tower is the third lighthouse at this location.  The first lighthouse at Cape Charles was a 55 ft masonry tower completed in 1828.  It was quickly deemed inadequate for its important seacoast location due to its low height and poor visibility at sea.  It was soon threatened by erosion so in 1864 it was replaced by a 150 ft masonry tower built further inland.  Located a little more than a mile southwest of the old tower and 600 feet from the shoreline, the impressive 150-foot-tall conical brick tower was similar in appearance to the 1857 Cape May Lighthouse, painted white and topped with a dark brown lantern room.  In 1892, a twenty-five-foot red band was painted around the white tower’s midsection, about sixty feet up from the base, to make it more visible during the day.  By the 1890s, it too was threatened by beach erosion which jetties built to protect it failed to halt, and with the lighthouse now only 300 feet from the ocean and the shoreline eroding at a rate of 37 feet per year it was decided that a third lighthouse needed to be built three quarters of a mile inland.

Typenturm: A Typenturm (German for "standard tower") is a standardised telecommunications tower built of reinforced concrete the former German federal post office (now Deutsche Telekom AG).  Different types of tower were developed and built at different locations, like the series FMT 1 to FMT 16.  The individual series differ in each case in the number of antenna platforms and the size of the operating projectile.  The types FMT 7 to 10 are without pulpit.  The type towers were usually designed on the basis of economic and functional criteria and only secondarily for aesthetics.  Compared with structural steelworks, the reinforced concrete construction way is easier in the establishment and maintenance.  In Germany there are about 300 towers of this type.  The establishment of these towers began in the mid-1960s, when the Federal Postal Administration developed its radio relay system clearly.  In the planning of the type towers engineer Fritz Leonhardt and the architect Erwin Heinle were considerably involved.  Examples of type towers are among other things: Köterberg (FMT 1), Ober-Olm (FMT 1/72), Hüfingen (FMT 1/73), Karlsruhe-Grünwettersbach (FMT 2), Waldenbuch (FMT 2/72), Hoherodskopf (FMT 2/73), Hemmoor (FMT 2/81), Hunau (FMT 3), Bielefeld (FMT 3/72), Gramschatzer Wald (FMT 5), Cleebronn (FMT 6), Seesen (FMT 7), Heidenheim an der Brenz (FMT 8), Saarlouis (FMT 8/73), Landau (FMT 9), Lahr/Schwarzwald (FMT 10), Fehmarn (FMT 11), sending refuge (FMT 12), Moers (FMT 13), Blauen (FMT 14), Schöppingen (FMT 15), Hamburg-Bergedorf (FMT 16) The communications towers in Münster, Kiel, Bremen and Cuxhaven were planned by an architect of the regional directorate Kiel and actually do not belong to this type of tower.  They are therefore called "Sondertürme", to which e.g. also the Rheinturm, the Heinrich-Hertz-Turm and the Fremersbergturm belong.  In addition, the telecommunication tower Koblenz reminded strongly of the type towers FMT 11 to 13, is a special tower, since it is larger substantially more highly and the pulpit than with the type towers.

Eiffel Tower (Cedar Fair): The Eiffel Towers at Kings Dominion and Kings Island are replicas of the Eiffel Tower in Paris, France.  They opened at Kings Island in 1972 and Kings Dominion in 1975, each when the park originally opened.

CBC Jarvis Street Tower: The CBC Jarvis Street Tower was a 160 m (540 ft) free-standing lattice tower built in 1952 to provide radio transmission facilities to the city of Toronto, Ontario, Canada.  It was the tallest freestanding structure in Canada for several years and the tallest lattice tower ever built in Canada.  In addition it was tallest structure in Toronto for 15 years until the completion of the TD Tower in 1967.  Owned by the Canadian Broadcasting Corporation, the tower was located at 345 Jarvis Street in the Church and Wellesley neighbourhood of Toronto.

Tower of Unity: The Tower of Unity (German: Turm der Einheit) is a 30 meter high observation tower on Heldrastein, a rocky mountain belonging to Treffurt in Thuringia.  The tower of Unity has an unusual history and is also from unusual design, because it is additionally guyed by anchoring wires, although it is actually free standing.  The tower of Unity was built in 1962 as transmitting tower for a radar station.  At that time it was an open steel lattice tower additionally guyed with the radar facility on its top.  The area of this tower was not accessible for tourists at those days as it laid in the restricted area of the former border between West and East Germany.  In 1989, when the border was opened, the area became again accessible for the public and the desire developed to build on Heldrastein again an observation tower, as there was until 1952 an observation tower built of stones, the such called Carl Alexander tower there.  In 1996 finally permission for the transformation of the radar tower into an observation tower could be received.  In order to do this changes, which cost 205,000 DM, the radome on the top was removed and the tower body was covered with wood.  In addition the tower got a stairway with 166 steps and an octagonal shelter at the tower basement.
