Lagny Abbey (St Peter’s Abbey, Lagny) was a monastery situated in the present-day commune of Lagny-sur-Marne in the department of Seine-et-Marne in France, in the eastern suburbs of Paris. It was founded in 644, refounded about 990 and after well over a millennium of existence (almost 1,150 years) was seized by the state at the French Revolution.
