There are three buildings within the Square. The old Nagahama station house is the oldest existing station house in Japan and its stationmaster’s room and waiting room are kept as they were in the old days. In the second building, the Nagahama Railway Cultural Pavilion, a large number of valuable materials about railways are exhibited. In the third building, the Museum for Commemoration of the Electrification of the Hokuriku Line, you can see steam locomotives which were in full operation before the line was made electric.
