This is a model kit of a building or other structure.
Academy's excellent kit of Korea's beautiful Namdaemun (Great Southern Gate), located in the center of Seoul. Originally built in 1398, it was burned down by a heartless arsonist in 2008. The kit features sharp molding in multiple colors, so a decent model can be built even without painting. Includes a stone wall base with nameplate, as shown here. Instructions are in Korean, but are pictorial and easy to follow.
