and the other labeled "1806," representing Washington College. The union of the two colleges is represented by a bridge between the two towers, with Roman numerals reading 1865, the year of union. Banners hanging from the towers show the college motto of "Juncta Juvant." The creation of the seal is unknown, with the first known use occurring during the 1902 centennial celebration of Jefferson College's founding. The seal is used in official documents, including diplomas and certificates. The college's current logo features a stylized version of the two towers of Old Main, symbolizing the 1865 unification of Washington College and Jefferson College. The logo may be displayed in several versions: with the entire name of the college, the shortened form of "W&J", or without any text. Prior to the adoption of this logo, the college's graphic identity consisted of a variety of conflicting logos and type styles. Relations with the city of Washington Relations between the city of Washington, Pennsylvania and Washington & Jefferson College span over two centuries, dating to the founding of both the city and the college in the 1780s. The relationship between the town and college was strong enough that the citizens of Washington offered a $50,000 donation in 1869 to the college in a successful attempt to lure the trustees to select Washington over nearby Canonsburg as the consolidated location of the college. The relationship encountered challenges the 20th century, with disagreements arising between the college and residential neighborhoods as the college pursued an expansion plan. Preservationists unsuccessfully attempted to pass laws prohibiting the college from demolishing certain buildings that were listed on the East Washington Historic District. Local preservationists also unsuccessfully tried to block the demolition of Hays Hall, which had been condemned. In the 1990s, the city of Washington made several unsuccessful attempts to challenge the college's tax-exempt status. In 1993, Washington appealed the Washington County Board of Assessment's determination that the college was exempt from the city's property tax. That case went to the Pennsylvania Supreme Court, which ruled in favor of the college. In response, the Pennsylvania General Assembly passed a new law clarifying that colleges were exempt from taxation, including from local property taxes. Separately, the city of Washington passed an ordinance that levied a municipal "service fee" against the college students, which was ruled to be illegal and was struck down. In the late 1990s, the college and town
