I will take a wild guess at what conference or war you mean, and say Paris, France.
The peace conference to end the First World War was held in and around Paris and was known as the Paris Peace Conference. Technically the war itself did not end until the signing of the Treaty of Versailles with Germany in 1919. (Versailles is a former royal palace near Paris). The other treaties with the Central Powers were also signed in and around Paris - the Treaty of Trianon with Hungary, the Treaty of Sevres with the Ottoman Empire, and the Treaty of Saint Germain with Austria.
because they could not come to terms on how to treat germany, 'the treaty of versailles?
if you mean the city it was in Paris (just like WW1) and was held etween July 29 to October 15, 1946

The 1919-20 conference that drew up the peace treaties following the First World War. http://www.u-s-history.com/pages/h1333.html A second Paris Peace Conference in 1946 drafted the peace treaties (signed the following February) between the Allies and Italy, Finland, Hungary, Romania and Bulgaria following the Second World War.
The Paris Peace Conference was held by the Allied Forces, who won the War; Austria had been on the defeated side and did not participate. However, the Treaty of Saint-Germain, which was signed at the Conference, redrew Austria's borders to recognize independence of certain territories, and ordered Austria to pay war reparations.
the Treaty of Versailles was one of the peace treaties made after WWI. It ended the war between the allied powers and Germany. It was signed on June 28, 1919. It was written in six months at the Paris Peace conference.
