Channel Islands Beach, California: Channel Islands Beach is an unincorporated community in Ventura County, California, United States consisting of three historic neighborhoods: Hollywood Beach, Hollywood by the Sea, and Silver Strand Beach.  This densely populated narrow 1.3 mi along the coastal edge of the Oxnard Plain was subdivided using the glamor of Hollywood to sell lots in the mid 1920s since the sand dunes had been used for movies.  Adjacent development has left this neighborhood hemmed in by Channel Islands Harbor and Naval Base Ventura County.  The harbor mouth separates them into two communities resulting in a round-about travel route around the harbor between them although the "Channel Islands Beach Community Services District" provides local utilities services to the entire neighborhoods.  The Special-purpose district has an elected Board of Directors which provides a forum for the unique concerns of the community.  Lying immediately adjacent but outside the corporate boundaries of the City of Oxnard and the City of Port Hueneme, they are governed by the county Board of Supervisors.

Samir Kassir Square: Completed in 2004, Samir Kassir Square is 815 square meters located in Beirut, Lebanon.  Vladimir Djurovic Landscape Architecture was responsible for the design.  The square acts as a gateway to Central Beirut.  The small square frames two ancient ficus trees which anchor the project.  The square’s design acts as a green urban oasis in a hectic city.  A serene space that reflects memories through its reflection of the skyline.  The trees act as shelters from the surrounding context.  A raised water feature adjacent to the street physically demarcates the boundaries.  Simple in design, the square creates an intimate space for contemplation and relaxation.

Pride of Baltimore: The Pride of Baltimore was a reproduction of a typical early 19th-century "Baltimore clipper" topsail schooner, a style of vessel made famous by its success as a privateer commerce raider and small but nimble warship in the War of 1812 (1812-1815), against British merchant shipping and a vastly superior world-wide Royal Navy.  Commissioned in an elaborate public ceremony in the historic Inner Harbor adjacent to downtown city skyscrapers, watched by thousands of Baltimoreans and Marylanders on May 1, 1977, by the 44th Mayor William Donald Schaefer (1921-2011, served 1971-1987) of Baltimore City, she spent nine years at sea logging over 150,000 miles, equivalent to six times around the globe.  On May 14 1986, the first "Pride of Baltimore" was lost at sea in the Caribbean Sea, and her Captain and three of the crew perished.

List of tallest buildings in Sunny Isles Beach: This article lists the tallest buildings in the coastal city of Sunny Isles Beach, Florida, USA, located in the northeast corner of Miami-Dade County.  The ranking primarily relies on data from The Skyscraper Center, the public online database of skyscrapers by the Council on Tall Buildings and Urban Habitat.  Supplementary data may be provided by Emporis, SkyscraperPage, or other third party news entities.  Sunny Isles Beach had very few skyscrapers until the 2000s, when many were constructed on the east side of Collins Avenue, on the beach adjacent to the Atlantic Ocean.  This strip historically consisted of a row of low rise hotels known as "Motel Row", mostly developed midcentury in the MiMo architectural style.  Even among high-rises, the oldest such structures in the city only date to the 1960s.  The wall of skyscrapers spans nearly the entire length of the city longitudinally, from the three Trump Towers located near the border of Haulover Park to the south to Regalia located adjacent to the border of Golden Beach to the north, which has strict single family residential zoning.  All the skyscrapers in Sunny Isles Beach are residential and all of them are primarily concrete structurally.  In general, the tallest height limit imposed by the Federal Aviation Administration (FAA) in Sunny Isles Beach is 649 ft Above Mean Sea Level (AMSL), due to the proximity of Miami-Opa Locka Executive Airport to the west.  Several proposed towers may rise to exactly this height, though the FAA reviews each building individually.
