Malta is a strictly Roman Catholic country and carousing by tourists, while tolerated to some extent, is not looked on very favorably, especially outside of St. Julian's and Paceville.
The native language is Maltese, and many would take offence if told that their language is Arabic or an Arabic dialect.

Dress respectfully when visiting churches. As a guide, remove any hats and sunglasses and make sure your knees and shoulders are covered. Some churches, especially those on popular package tours, provide shawls and/or skirts for any inappropriately-dressed visitors.

You may be refused entry to a church if there is a service going on that has already started, make sure you arrive promptly if you wish to see them.

ɧoɱosɛҳųαƖity is tolerated, but the people do not fully accept it. It is inappropriate to display affection between same sex persons publicly.  :cry:
