Narrative:

Aircraft was conducting a visual approach. I instructed the pilot to continue inbound to the airport and report 3 northeast which is outside ZZZ1 airspace and inside ZZZ; all while scanning the area for the aircraft. The pilot reported he was 3 northeast and i subsequently cleared him to land. I continued to scan the airspace along with the controller in charge. Moments later the MSAW alarm activated for a low warning altitude warning. I scanned the airspace from the approach end of runway 09 to approximately the VORTAC which is located approximately 3 northwest a few seconds later the pilot said he was on the ground and i asked where; he said at the airport. I asked 'which airport ZZZ or ZZZ1?' his response was 'I thought I was at ZZZ'. I dialed the ZZZ1 tower and told them they just had an airplane land there mistakenly. I believe the pilot may have become disoriented due to the low cloud layer and hazy conditions. Additionally; when an aircraft is cleared for the visual approach the approach control facility should verify to the pilot that they have the single runway airport in sight. Finally; the radar monitoring screen we have in the tower sits very high and blocks a portion of the runway. A person who is of average height may or may not be able to see 100 percent of the runway or an aircraft entering a right base to runway at ZZZ or a left base to runway at ZZZ1 airport 2 miles away to the east. I was standing and am not able to see an aircraft entering the left base for runway at ZZZ1. If I were able to see over the radar screen I may have been able to alert the pilot prior to touchdown or any critical phase of flight. I reserve the right to change my statement upon listening to the recorders if the case be; and to change my statement should others facts be presented.
