7 World Trade Center (1987–2001)

7 World Trade Center (7 WTC, WTC-7, or Tower 7) refers to two buildings that have existed at the same location within the World Trade Center site in Lower Manhattan, New York City. The original structure, part of the original World Trade Center, was completed in 1987 and was destroyed in the September 11 attacks in 2001. The current structure opened in May 2006. Both buildings were developed by Larry Silverstein, who holds a ground lease for the site from the Port Authority of New York and New Jersey. The original 7 World Trade Center was 47 stories tall, clad in red granite masonry, and occupied a trapezoidal footprint. An elevated walkway spanning Vesey Street connected the building to the World Trade Center plaza. The building was situated above a Consolidated Edison power substation, which imposed unique structural design constraints. When the building opened in 1987, Silverstein had difficulties attracting tenants. Salomon Brothers signed a long-term lease in 1988 and became the anchor tenant of 7 WTC. On September 11, 2001, the structure was substantially damaged by debris when the nearby North Tower of the World Trade Center collapsed. The debris ignited fires on multiple lower floors of the building, which continued to burn uncontrolled throughout the afternoon. The building's internal fire suppression system lacked water pressure to fight the fires. The collapse began when a critical internal column buckled and triggered cascading failure of nearby columns throughout, which was first visible from the exterior with the crumbling of a rooftop penthouse structure at 5:20:33 pm. This initiated progressive collapse of the entire building at 5:21:10 pm, according to FEMA,: 23  while the 2008 NIST study placed the final collapse time at 5:20:52 pm.: 19, 21, 50–51  The collapse made the old 7 World Trade Center the first steel skyscraper known to have collapsed primarily due to uncontrolled fires.Construction of the new 7 World Trade Center began in 2002 and was completed in 2006. The building is 52 stories tall (plus one underground floor), making it the 28th-tallest in New York. It is built on a smaller footprint than the original, and is bounded by Greenwich, Vesey, Washington, and Barclay Streets on the east, south, west, and north, respectively. A small park across Greenwich Street occupies space that was part of the original building's footprint. The current building's design emphasizes safety, with a reinforced concrete core, wider stairways, and thicker fireproofing on steel columns. It also incorporates numerous green design features. The building was the first commercial office building in New York City to receive the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) certification, where it won a gold rating. It was also one of the first projects accepted to be part of the Council's pilot program for Leadership in Energy and Environmental Design – Core and Shell Development (LEED-CS).

The Ronald O. Perelman Performing Arts Center at the World Trade Center (PACWTC), also called the Performing Arts Center and 6 World Trade Center, is a multi-space performing arts center under construction at the northeast corner of the World Trade Center complex in Manhattan, New York City. The Performing Arts Center is located at the intersection of Vesey, Fulton, and Greenwich Streets in Lower Manhattan. The building is named for billionaire Ronald Perelman, who donated $75 million to its construction. Plans for the Performing Arts Center were first announced by the Lower Manhattan Development Corporation (LMDC) in 2004 as part of the rebuilding of the World Trade Center site after the September 11 attacks. Gehry Partners LLP and Snøhetta were selected as the original designers, but plans were reportedly stalled over financing and design, as well as the presence of the temporary entrance to the PATH train's World Trade Center station on the site. The original design was scrapped by September 2014, and Joshua Prince-Ramus and Davis Brody Bond were selected as architects the next year. After further financing issues were resolved and the PATH station entrance was relocated, below-ground construction began in August 2017, followed by the construction of the above-ground frame in 2020. It is scheduled to be completed in late 2022 and open in 2023. When completed, the Performing Arts Center will include approximately 90,000 square feet (8,400 m2) across three floors.

The Park Place disaster occurred on August 22, 1891, in New York City when benzene vapor from a bronze powder manufacturer ignited, causing an explosion that resulted in the collapse of the five-story Taylor Building that housed the manufacturer along with other businesses. Two fires then broke out, one in the ruins of the manufacturer and the other in a restaurant that was caused by a natural gas leak. The disaster killed 61 people, while local residents were admonished in the press for rubbernecking and general insensitivity. A grand jury declined to indict any of the owners or occupants of the building, however legislation was introduced in the New York State Assembly that sought to tighten the building code in light of this disaster and the 1892 Hotel Royal fire.
