The initiative to downsize comes as Baltimore sees a decrease in its population.
According to the Archdiocese of Baltimore, Catholic churches in the city and surrounding suburbs were built to serve a growing population.
In the 1950s, over a dozen churches opened to accommodate a population boom that pushed the city to nearly 1 million residents.
Since then, Baltimore's population has shrunk to less than 570,000 people, prompting the downsizing initiative and eventually the announcement of a final plan in May 2024.
Baltimore Archbishop William Lori also attributed the decision to deteriorating buildings and the cost of maintaining aging churches.
"...this process was aimed at allowing our parishes to focus on mission and ministry, as opposed to leaking roofs, crumbling walls and failing electric and plumbing systems," Baltimore Archbishop Lori said in his announcement.
