What was Martin Luther impression of the Vatican City when he visited?

Martin Luther's impression of Vatican City during his visit in 1510 was one of profound disillusionment. He was struck by the opulence and wealth of the Church, which he believed contrasted sharply with its spiritual mission. Luther felt that the focus on material riches and the corruption within the clergy undermined true Christian values, leading him to question the authority of the Pope and the practices of the Catholic Church. This experience later fueled his reformative ideas and critiques of the Church.
