Passive Voice – Why ‘He Was Seen to Break the Window’ Uses Infinitive

We normally use the passive with verbs that express the idea of agency: something done to {someone or something} by {someone or something else}.

Have, in the sense of "to be in possession of", although transitive, does not involve a doing-to, and for that reason it does not lend itself to passive expression.

On the other hand:

He bought the book

can become

The book was bought by him.

He took the book. The book was taken by him.

Out of context, it would be logical to assume that this is the adjective as a consequence of past events, in that "the city was burned" by someone or something and is now being described as "burned". A present construction in the passive voice would yield "the city is being burned (to the ground)". Another possibility in the passive voice is that "the city is burned every few years", again dependent on the context, which you have not included.
