A "titular church" is a church in Rome that is assigned to a cardinal, who is a high-ranking official in the Catholic Church. These churches are often historical and significant, serving as a symbol of the cardinal's connection to the city and the church community. Titular churches are part of the Roman Catholic tradition, where cardinals are given the title of a specific church to represent their role in the church hierarchy. This practice dates back to the early centuries of Christianity and helps maintain the connection between the Vatican and local parishes.
