This is a model of the stratum which was excavated near this museum. Layer IV shows the Great Fire in 1657. In Layer 0, we can see the burnt ground by the fire after the Great Earthquake in 1923 and also the burnt ground by the air raid of World War II in 1945.
In the middle of the 18th century, some row houses were built around here. At the center of Layer II, we can see the ruins of a sewage pipe.
On the other side, the ruins of a well can be seen.
The artefacts displayed in the case were found at the time of excavation.
