Answer 1

O It was surrounded by water on three sides.

Step-by-step explanation:

Constantinople was strategically located between the Golden Horn and the Marmara Sea, which meant that it was surrounded by water on three sides of the city. This hindered the invasion, since the possible invaders should have an organized navy. Despite this privileged location, in order to reinforce its defenses and prevent naval attacks, very high and resistant walls were built that surrounded the city on all sides and had a double wall and a staked moat. In addition, the city was built between seven hills.

All of these factors made invasions more difficult and made the constantinople possess one of the most complete and complex defense systems of antiquity.
