Young women hold shields with the names of the towns that became part of Jersey City, including the old Dutch settlements of Paulus Hook, Van Vorst and Bergen, and the later (largely German) Hudson City and Greenville. The city was first incorporated in 1820 and consisted only of Paulus Hook. In 1851 neighboring Van Vorst Township was added, followed in 1870 by Bergen and Hudson City. Jersey City reached its current boundaries in 1873 with the addition of Greenville. In October, 1910 Jersey City celebrated the 250th Anniversary of its founding as the town of Bergen by the Dutch in 1660. Children from Public School # 11, on the oldest continual school site in New Jersey, presented tableaux commemorating the early events in the city's history. The exercises were presented at Bergen Square, the heart of the original settlement, to an audience numbering over 15,000.
