Mission San Francisco de Asís Celebrates 250
San Francisco Marks 250 Years: Celebrating the Founding of Mission Dolores and the Birth of a City
This October 9 and 10, San Francisco will commemorate a remarkable milestone: the 250th anniversary of the founding of Misión San Francisco de Asís, commonly known as Mission Dolores. The anniversary recalls October 9, 1776, when the mission was formally opened, establishing a religious community alongside the newly created Presidio and helping form the nucleus from which modern San Francisco would develop. Mission Dolores today describes October 9, 1776, as its founding date, and the surviving mission church remains the oldest intact building in San Francisco.
The story actually began several months earlier. An expedition led north by Juan Bautista de Anza brought settlers, soldiers and Franciscan missionaries to the San Francisco Peninsula. On June 27, 1776, the colonizing party reached the area, and two days later Father Francisco Palóu celebrated Mass near the Laguna de los Dolores. The military settlement developed separately at the Golden Gate, and the Presidio of San Francisco was formally established on September 17, 1776. Finally, on October 9, the mission was formally opened. Together, the mission and presidio represented Spain’s northernmost major foothold in Alta California and laid the foundations for what would become San Francisco.
The anniversary has an extraordinary connection to the broader history being commemorated across the United States in 2026. San Francisco’s Spanish settlement occurred in the same year as the American Declaration of Independence. While a new nation was emerging on the Atlantic coast, Spain was establishing the Presidio and Mission San Francisco de Asís on the Pacific. The Presidio itself notes that its founding unfolded at the same time the Declaration was being signed in the East. Thus, in America’s Semiquincentennial year, San Francisco is simultaneously commemorating 250 years of its own recorded colonial history and 250 years since the founding era of the United States.
That history also reaches much further back than 1776. The San Francisco Peninsula was and remains the ancestral homeland of the Ramaytush Ohlone, including the Yelamu people who inhabited the area long before the arrival of the Spanish. The mission era profoundly transformed Native communities throughout the region. Today, the Mission Dolores cemetery is the final resting place of numerous Ohlone, Miwok and other First Californians, making the anniversary an opportunity to reflect upon the many peoples and cultures whose histories intersect at this extraordinary place.
The principal anniversary observances will center on Friday, October 9, 2026—the actual 250th anniversary date. At 12 noon, Mission Dolores Basilica will host an Ecumenical Thanksgiving Prayer Service with interfaith and civic leaders, bringing together the broader San Francisco community to commemorate the historic occasion. The service is particularly appropriate for an anniversary that extends beyond the history of one parish or one faith: October 9 marks a pivotal moment in the development of the community that eventually became one of America’s great cities.
Celebrations will continue on Saturday, October 10, at 11 a.m., with a major concelebrated Mass at Mission Dolores Basilica. Archbishop Salvatore J. Cordileone will preside and celebrate, with Bishop Michael C. Barber, S.J., Bishop of Oakland, serving as homilist. The liturgy will feature the Missa Sancti Juniperi Serra and sacred music associated with the Benedict XVI Institute. A reception will follow. The Mass will also be carried by EWTN, extending the 250th-anniversary commemoration well beyond San Francisco.
The October weekend forms the culmination of a much broader anniversary year at Mission Dolores. A special museum exhibition opened in May, and a concelebrated Mass honoring the mission’s founding was held June 27. The October observances begin with Morning Prayer for St. Francis of Assisi on Saturday, October 3, at 11 a.m., followed on Sunday, October 4, at 11 a.m. by a bilingual Spanish-English Mass and procession. The October 9 interfaith service and October 10 anniversary Mass then bring the celebration to its historic climax.
Two hundred and fifty years later, the Mission, the Presidio and the city that grew around them remain enduring reminders of San Francisco’s complex and remarkable beginnings. The anniversary offers an opportunity not simply to celebrate a date, but to recognize the Native, Spanish, Mexican and American chapters that have shaped San Francisco across centuries. As Mission Dolores marks 1776–2026, the commemoration connects the city’s beginnings with America’s own 250th anniversary and reminds us that the history of the United States was unfolding on both sides of the continent in that consequential year of 1776.
