The Arch 1979–1980 (LH 503c)[1] is a large stone sculpture by Henry Moore located in Kensington Gardens, London.

In a 1980 interview Moore said that "After the 1978 exhibition at the Serpentine Gallery in London, in which several large pieces were located in Kensington Gardens, there was a request for me to leave a sculpture there permanently, which I agreed to do.

I thought the Large Arch was very naturally sited, particularly as it could be seen reflected in the water from across the lake.

Therefore, so that it could be left as a permanent sculpture in Kensington Gardens, I produced a version in travertine marble which is a very lasting material.

"[3] The Arch was found to be unstable in 1996, and was subsequently dismantled and placed into storage.
