There was an official update that allows you to build a statue in every village...
And there was an old glitch that I learned about a long time ago (when only 1 statue was possible) that allowed you to make a negative statue. I am unsure if it still works though.
Whenever you nobled a village, they would downgrade the statue, if it existed, to level 0. However, if the previous owner was in the process of demolishing the statue, it would continue to be demolished, resulting in a negatively leveled statue. Interestingly this glitch allowed you to build a second statue even if you already had a first one. Apparently a level 1 statue in one village and a level -1 statue in another village is equal to no statue to the game, allowing for the construction of an additional statue.
