When it comes to active sentences, you have your subject, your verb, and your direct object. However, when you want to make a passive sentence, you should place the direct object in the initial position (acting as something similar to a subject) to place emphasis on that particular word.
So, in the active sentence, the subject was some artist, the verb was painted, and the object was the mural.
