The Isabella Stewart Gardner Museum in Boston was designed by Willard T. Sears for Isabella Stewart Gardner, whose will required the collection to be displayed for the education and enjoyment of the public forever. The infobox gives 1896 to 1903, while the text says 1898 to 1901. It opened on January 1, 1903.
The article describes a 15th-century Venetian palace. It uses new materials plus architectural elements from European Gothic and Renaissance buildings, custom floor tiles, modern concrete and a glass courtyard roof on steel supports. It gives no dimensions for the original building. The 2012 Renzo Piano wing adds 70,000 square feet.
The building reached the National Register in 1983. The unsolved 1990 theft took 13 works, and the 2012 expansion cost 118 million dollars. It is an art museum with concerts and education programs. Anyone named Isabella is admitted free for life. The article gives no hours.
