Calçada das Verdades begins between Rua de S. Domingos and Rua de Pedro Nolasco da Silva, opposite Beco da Arruda, and ends in the upper section of Calçada do Monte, close to Caminho dos Artilheiros. About 270 metres long and approximately 5 metres wide, it is a small lane stretching south-north. Originally known as Na Tcha Temple Street, it was renamed Calçada das Verdades during the tenure of the Governor of Macao António Sérgio de Sousa (1868-1872). Its name was recorded in “Cadastro das Vias Públicas de Macau” (Cadastre of Public Roads of Macao) published in 1957. The Portuguese name “Calçada Das Verdades” means “sloping lane of truth”.
The Na Tcha Temple in Calçada das Verdades is one of the two remaining Na Tcha Temples in Macao. It looks more like a Chinese pavilion than a traditional temple. Inside, the pavilion is equipped with worship facilities such as shrines, worship tables, and censers. The temple is supported by six stone pillars, with four of them carved with couplets and the other two hung with woodcut couplets.
In 2014, the Na Tcha Customs and Beliefs of Macao were included in the “Fourth Batch of the National List of Intangible Cultural Heritage of China”. On 18th day of the 5th month of the lunar calendar each year, the Associação do Templo da Calçada das Verdades de Macau holds a series of activities in celebration of the Feast of Na Tcha such as the Na Tcha seal opening ceremony, prayers for good luck, procession of the statue of Na Tcha, plays for the gods, prayers for Na Tcha paper amulets and distribution of blessed rice.
