Departed to ZZZ. Flight conditions were clear and calm. Upon arrival to into Class B airspace; Approach Control was very busy. We had multiple heading turns and a descent down to 1500 feet. We were unfamiliar with the airport ZZZ and ATC cancelled flight following. At this time we were over the airport and not aware of our position which was the wrong airport. My student pilot and I spotted the runway and continued to approach and land. The runway we landed on was 22 the runway we were supposed to land on was 23... which was ZZZ1 Air Force Base. I realized as soon as we landed that we were at the wrong airport. The Tower and the Base was closed on Sunday but we did have security meet us. We were detained and fined $250. We were assured this happens often but do not plan on it happening to us again.
PA32 Flight Instructor reported misidentifying landing runway resulting in unauthorized landing at military base.
