2 Best Sights in Las Vegas, Nevada

Guardian Angel Cathedral

The Roman Catholic cathedral often has standing-room only on Saturday afternoon, as visitors pray for luck—and sometimes drop casino chips into the collection cups during the tourist-friendly mass. According to tradition, a priest known as the "chip monk" periodically collects the chips and takes them to the respective casinos to cash them in. There are daily masses, with three on Sundays.

Shrine of the Most Holy Redeemer

Churchgoers staying in the South Strip area stagger into this beautiful Roman Catholic church for mass seven days a week. Among the more popular offerings: the four Sunday masses in English and one in Spanish.
