I've just found out what it is. It is called Tongshipjagak (or Dongsipjagak) Pavilion, literally the East Cruciform Pavilion. It was first built in 1395 by the first king of the Choson (or Joseon) dynasty as a watchtower, then without the upper pavilion part. It was within the Kyongbok (or Gyeongbok) Palace walls. The pavilion was added in 1867 by King Kojong (or Gojeong). The Japanese came and reduced the size of the palace complex, by destroying many buildings or moving structures such as the Kwanghwamun Gate and parts of the walls from their original sites. As a result the Pavilion is now outside the palace walls. It is now about 20 metres off the southeast corner of the palace walls, and right in the middle of an intersection of streets.
