The diocese stretches from the southern edge of Sacramento County north to the Oregon border and serves approximately 1,000,000 Catholics.

[8] With a recent restoration project that loops together the Catholic culture, the legacy of gold miners, visions of a vibrant downtown and the sentiments of Sacramentans who spent some of life's most memorable moments within the church's walls, the Cathedral of the Blessed Sacrament combines Sacramento's history with its modern-day life.

His goal was to earn enough money to finance a trip to Paris, where he planned to enroll in seminary college and become a Roman Catholic priest.

Inspired by churches he'd seen in European plazas, Manogue worked to secure property just one block away from the State Capitol, with a dream of building a cathedral in Sacramento.

Manogue modeled the cathedral after L'Eglise de la Sainte-Trinite (The Church of the Holy Trinity) in Paris.

From August 2003 until November 2005, the cathedral closed for extensive remodeling to unify the church's décor from the numerous renovations throughout the years.

Every part of the cathedral was updated in the restoration ranging from expanded pews to better lighting with decorative painting on the interior walls and ceiling.

The dove in the oculus, with a wingspan of 7 ft (2.1 m), is “a dramatic reminder of the Holy Spirit’s presence in the life of the church, especially in the celebration of the Eucharist,” according to Father James Murphy who was the rector of the cathedral during its renovation.

Workers used a powerful epoxy with the steel to bond components to the structure and enable the building to withstand an earthquake measuring 8.0 on the Richter scale.
