evidence: Saint-Laurent-du-Maroni (French pronunciation: [sɛ̃ loʁɑ̃ dy maʁɔni], lit. 'Saint-Laurent of the Maroni'; French Guianese Creole: Sen-Laurent-di-Maronni) is a commune of French Guiana, an overseas region and department of France located in South America. Saint-Laurent-du-Maroni is one of the three sub-prefectures of French Guiana and the seat of the Arrondissement of Saint-Laurent-du-Maroni. It is the second most populous city of French Guiana, with 50,250 inhabitants at the January 2021 census.[3] [...] Geography [edit]Saint-Laurent-du-Maroni is a border town in north-west French Guiana. It is located on the Maroni River (in Dutch: Marowijne), opposite the town of Albina in Suriname which can be reached by ferry or pirogue.[8] It does not, therefore, have an Atlantic coast; this may have motivated the choice of the town's location, as the penal authorities wanted to prevent the escape of prisoners from the Prison of St-Laurent-du-Maroni by a sea route.[7] [...] Other notable sights from the penitentiary years include Saint-Jean-du-Maroni, formerly the Camp de la Relégation and today's main military HQ for western French Guiana. There is also a small island in the middle of the Maroni River which used to house the prisoners affected with leprosy. Papillon wrote about hiding there during one of his daring escapes.[30]
