What should I built in my minecraft city?

A STATUE OF YOURSELF TO SHOW YOUR DOMINION OVER All OTHERS

Take out a map of the city you live in and get ideas from there.
Example: Government buildings, public service buildings (police station, fire station), parks, lakes, canals, banks, restaurants, open air markets, supermarkets, thrift shops, statues, castle, forest/mountain trail, shopping malls, arcade, schools, apartments, mansions, public bathrooms, stores, tourist stores, amusement parks, hotdogs stands… Seriously, the possibilities are endless
