在 1998 年安妮·冈萨雷斯 (Anne Gonzalez) 的一篇文章中，她报告说：“萨克拉门托罗马天主教教区已着手对位于第 11 街和 K 街的这座拥有 109 年历史的大教堂进行评估。这项研究将于 9 月底完成，将成为教堂翻修的框架，特别是其独特的 115 英尺高的圆顶。该项目可能需要多年的资金筹集和研究，才能对一座历史长期被时间、天气、以前的修改和缺乏准确记录所掩盖的建筑进行研究。”
计划和执行花费了 5 年时间，耗资 3400 万美元，并要求教区在邻近的教堂敬拜两年，但结果令人震惊，并确保大教堂将在下一个世纪甚至更久之后仍然屹立不倒。

The Baptismal Font & Well
Placed at the entrance of the cathedral to represent entry into the church through baptism demonstrates the importance of this sacrament. The font is a working fountain reflecting Psalm 42, "Like the deer that yearns for flowing water, so my soul is yearning for you my God."
Left: In 1808. Spanish army officer and explorer Gabriel Moraga discovers and names the Sacramento River because "Es como el sagrado sacramento (This is like the Holy Sacrament)." Right: In 1850, Father Peter Anderson founded St. Rose of Lima Church, the first church in Sacramento, after Peter Burnett, the first governor of California, and a Catholic, gave Father Anderson a lot at 7th and K Streets.
Electric power came to Sacramento in 1895. Until then, the cathedral was illuminated by gas lights. No information on when electric chandeliers were added, but the ones hanging in the cathedral now were refurbished and revamped during the 2005 renovation, including the addition of an outer ring around the incandescent lights.
The Dome Restored
While no pictures of the original dome were found, descriptions in newspapers helped designers recreate an inspiring dome motif. Sixteen roundels, each five feet tall, tell the story of the Eucharist, with corresponding bible verses. The 24-foot oculus at the top allows indirect light to illuminate the digital photograph meant to resemble stained glass.
The Eucharistic Chapel
This space was where the original altars were located, until Vatican II moved the altar to the center of the assembly. This space was largely wasted until the renovation when designers added the Eucharistic Chapel surrounding the tabernacle. It is used for small Masses or events, or private meditation and prayer.
The Martyr's Chapel (South Side)
The mural is of the Risen Christ and Martyr's of the ancient Church and from around the world. The devotional crucifix is deliberately placed for people to touch it. The wood altar here and in Mary's Chapel are from 1889 and were in storage after the 1939 redecorating. In 2005, they were reinstalled and painted to look like marble.
The organ is the third one to grace the cathedral. The first was built by J.C. and H.S. Odell for the St. Rose of Lima church, and was installed in the cathedral ten years later. It was replaced by a Schlicker organ in 1977. That one was rebuilt and nearly doubled in size during the 2005 renovation.
On the top of the four columns are the pendatives, which are curved triangles of vaulting formed by the intersection of a dome with its supporting arches, painted with representations of the four Gospels - Matthew, Mark, Luke, and John. On the columns, representations of the sacraments - Baptism, Holy Orders, Marriage, Confirmation, Anointing the Sick, Confession, and Communion.
The Statues of the Saints
The position of each statue has changed over the years, but they are original to the cathedral, and have been restored. As well as the Blessed Mother and Sacred Heart on either side of the east end, there is also St. Patrick, St. Joseph, St. Anthony, and Our Lady of Mt. Carmel.
