Monte Serrat, Summit and religious landmark in Santos, Brazil.

Monte Serrat is a hill in Santos, Brazil, with a small chapel, a viewing terrace, and a former casino building at its top. Both a funicular railway and a stairway of roughly 415 steps connect the base to the summit facilities.

The summit chapel dates to 1603, built at the request of Dom Francisco de Sousa, governor-general of Brazil from 1599 to 1605. A casino operated on the hill in the 19th century and was later closed. The funicular was planned in 1910, built in 1923 by the Elevador Monte Serrat company and inaugurated in June 1927; after casinos were banned following World War II, that company became a family business.

The hill's name comes from the Virgin of Montserrat, invoked by residents who fled up the slope during a raid; the attackers were said to be crushed by falling rocks. She became patron saint of Santos, and her feast is held on 8 September at the sanctuary on the summit.

The summit can be reached by funicular or on foot via a long stairway, so it helps to choose based on your pace and how much you want to stop along the way. Mornings tend to offer clearer views over Santos and the surrounding coast.

A local legend says that rocks tumbling down the hill once stopped a pirate attack on the city, which is why the site came to be seen as protective. This story has been passed down by word of mouth and is still part of how many locals explain the hill's spiritual meaning.
