Answer 2

Most castles no longer have their original art, but each remaining noble still takes pride in its heritage.

Possessive adjectives are those adjectives that show a belonging relationship in an ample sense. In this case the first sentence uses their because it is talking about castles. In the second sentence it is better to use its because it is stating each which is singular.
