This bullet-shaped skyscraper in the Sant Martí District was named Torre Agbar when it opened in 2004 as the headquarters of Grupo Agbar, an international water treatment company. Architect Jean Nouvel claims his design resembles a geyser. The unique, 472 foot façade features 4,500 windows with temperature-controlled levers and an equal number of LED lights that illuminate at night. Barcelona’s third tallest building was renamed Torre Glòries in 2017 after the office high-rise was purchased by Merlin Properties.
