The Carioca Aqueduct, also known as Arcos da Lapa, is a historic structure located in the Lapa neighbourhood of Rio de Janeiro, Brazil. Originally built in the mid-18th century to transport water from the Carioca River to the city, it is an example of colonial architecture. Today, the aqueduct serves as a bridge for the Santa Teresa Tram, offering visitors a unique way to explore the area. Tourists can enjoy a ride on the tram, which provides scenic views of the city and access to the charming Santa Teresa district, known for its narrow streets, colonial houses, and vibrant arts scene.
