The current Town Hall is the former episcopal palace, the construction of which was launched by Monsignor Scipion Jérôme Bégon in 1739 based on plans by Nicolas Pierson. Around the park's central pond, begonias recall the link between Toul and these flowers, which number many. The park also boasts a rich tree heritage, including the Ginkgo biloba, labeled "Remarkable Tree of France." The Toul Ginkgo biloba is said to have been brought back from Toulon by Admiral Henri de RIGNY, born in Toul in 1782, victor of the Battle of Navarino in 1827, Minister of the Navy and then of Foreign Affairs under Louis-Philippe.
