text: Around Jalan d 'Albuquerque and Dataran Portugis ( Portuguese Square ) , the houses look no different from those in the rest of Melaka , but you may hear snatches of Cristao , a 16th-century Portuguese dialect , and mothers calling out to Afonso , Luis , or Filomena .

  The homes around Portuguese Square are occupied only by people who speak Cristao .
