Prudential Tower: The Prudential Tower, also known as the Prudential Building or, colloquially, The Pru, is an International Style skyscraper in Boston, Massachusetts.  The building, a part of the Prudential Center complex, currently stands as the 2nd-tallest building in Boston, behind 200 Clarendon Street.  The Prudential Tower was designed by Charles Luckman and Associates for Prudential Insurance.  Completed in 1964, the building is 749 ft tall, with 52 floors.

Kirya Tower: Kirya Tower (also known as the HaYovel Tower) is a skyscraper in Tel Aviv, Israel.  At 158 m (42 floors), it is the sixth tallest building in Israel.  Construction was completed in 2005 on land previously belonging to the IDF HaKirya base.  The tower is located near the Tel Aviv's tallest skyscraper cluster, the Azrieli Center complex, and is occupied largely by government offices.  The consolidation of many of these offices in the tower, which were previously spread out all over the Tel Aviv district, allowed the release of a considerable amount of high-value government land to private development, as well as introducing efficiencies from housing many government functions under one roof.  The tower has a helipad on its roof.  It was originally planned to have 28 floors for government functions only, with the additional 14 floors being approved during construction.  13 of these top floors were approved for use by private sector offices, and the top 11 floors have floor-to ceiling windows.  An external elevator serves the uppermost floors, and an underpass connects the building with the tower's underground parking.  The rent being paid by the government is $16/square metre per month for the next 20 years.

Grant USA Tower: The Grant USA Tower was a proposed 121-story skyscraper planned for Newark, New Jersey by developer Harry Grant.  Harry Grant was an Israeli-born developer who was based out of New Jersey, and who financed the gold dome on top of Newark City Hall, and also started the never-completed Renaissance Mall in the city.  Grant Tower was to be located over the old Central Railroad Terminal, near Broad and Lafayette Street.  In 2007, the incomplete Renaissance Mall was torn down to build the Prudential Center.  The old and unused part of the train station below, which was to serve as the foundation of the tower, remains in place.  There are currently plans to connect the old portion of the train station with the Prudential Center, with the idea of turning it into a museum.  There were plans for a 21-floor atrium above the 121st floor, which would have been the top floor of the hotel.  Had it been completed as planned by 1986, it would have contained the tallest hotel, and would have been the tallest building and the tallest structure at the time.
