Fulcrum (1987) by Richard Serra, is a site specific sculpture commissioned for the west entrance to Liverpool Street station in the Broadgate complex. The sculpture is 55 ft (16.8 m) high, and constructed from five plates of Cor-ten steel which intentionally have rusted to add patina to the surfaces. Although each plate weighs many tons, the sculpture is free-standing with the plates leaning against each other at the top. (Keywords: Richard Serra, modern sculpture, cor-ten steel)

The photographic reproduction of this work is covered under United Kingdom law (Section 62 of the Copyright, Designs and Patents Act 1988), which states that it is not an infringement to take photographs of buildings, or of sculptures, models for buildings, or works of artistic craftsmanship permanently located in a public place or in premises open to the public. This does not apply to two-dimensional graphic works such as posters or murals. See COM:CRT/United Kingdom#Freedom of panorama for more information.
This work might not be available under a free license in the United States because it is based on an artwork or sculpture that may be protected by copyright under U.S. law. (Commons is hosted in the United States and as such, U.S. law is applicable.)
In the source country of the artwork or sculpture, taking photographs of such works permanently located in a public place does not generally infringe on their copyright, under a principle known as "freedom of panorama".
In U.S. law, there is no freedom of panorama for artwork or sculptures, and under the choice-of-law principle lex loci protectionis, U.S. courts might apply U.S. freedom of panorama standards to this work, rather than the standards of the source country. However, in practice, it is unsettled whether and how this approach would be applied in real-world U.S. legal cases involving freedom of panorama elements.
The current policy on Commons is to accept photos of artwork and sculptures that are covered by freedom of panorama in their source country. This policy may change in the future, depending on the outcome of community discussions and new case law.
This is not a valid license tag on Commons; this file must be usable under freedom of panorama in its source country or it will be deleted.
