The London Guarantee Building or London Guaranty & Accident Building is a historic 1923 commercial skyscraper whose primary occupant since 2016 is the LondonHouse Chicago Hotel. Formerly known as the Stone Container Building, it is located near the Loop in Chicago, and is one of four 1920s skyscrapers that surround the Michigan Avenue Bridge (the others are the Wrigley Building, Tribune Tower and 333 North Michigan Avenue) and is a contributing property to the Michigan–Wacker Historic District.

The London Guarantee & Accident Building was designed by Chicago architect Alfred S. Alschuler and completed in 1923 for the London Guarantee & Accident Company, an insurance firm that was then its principal occupant. The top of the building resembles the Choragic Monument of Lysicrates in Athens, but it is supposedly modelled after the Stockholm Stadshus. (wikipedia.org).
