Introduction to Longhuan Portuguese Charm: Longhuan Portuguese Charm Residential Museum was opened to the public on December 5, 1999. It is a museum based on five Portuguese-style houses on the seaside road. "Dragon Ring" is the old name of Taipa Island, and "Portuguese Rhyme" refers to the Portuguese architectural style here. The five Portuguese-style buildings here were completed in 1921. They were originally the official residences of senior officials from the outlying islands of Macau and the residences of some Macanese families. In 1992, the Macao-Portuguese government restored and renovated the building complex and turned it into a unique museum.
