1774. The looming War of Independence halted further construction, however, and the fourth wing was never completed. The foundations, however, still exist and were uncovered during excavations in 2014. The first and second floors of the building are still open for public viewing.

Uses of the building The Wren Building is the oldest extant building constructed for use by a college or university in the United States, ahead of runner-up Massachusetts Hall at Harvard. The Wren Building, previously known simply as "The College" or "The Main Building" was effectively the school's only academic building until the completion of the Brafferton building and President's House in the 1720s and 1730s. The campus only began its westward expansion in the first part of the twentieth century. Students studied, attended religious services, and lived in the Wren Building. In addition, at least eight students brought their enslaved people at the cost of room and board. After the destruction of Virginia's former capital of Jamestown, Virginia's legislature met in the building's Great Hall as a temporary meeting place from 1700 to 1704 while the Capitol was under construction. In fact, the College was critical to Williamsburg becoming the new capital of Virginia after William & Mary students made speeches on May 1, 1699 from the College Building about how they would help build the town to its full potential. When the Capitol burned in 1747, the legislature moved back into the building until the Capitol was reconstructed in 1754. The building also housed a grammar school and an Indian school, which was moved to the Brafferton building, in 1723. The building was used as a military hospital by the French during the American Revolutionary War and by the Confederacy during the American Civil War. The Wren Building today has historical and ceremonial importance in addition to its academic use. Each year during the opening convocation ceremony, incoming William and Mary freshmen enter the building from the courtyard, pass through the central hall, and exit on the opposite side. As seniors, students pass through the building in the opposite direction on their way to the graduation ceremony. The Yule Log Ceremony, the College's holiday
