Historical Monster Telescope The 65cm Big Telescope Dome
The 65 cm Big Telescope Dome, Taisho 15 (1926) The 65 cm Telescope Dome is a giant building; it is 19.5 m high and has a dome with an impressive diameter of 15 m. At the time of construction, the builders did not have the skill to create a semi-spherical dome, so shipbuilders skilled in making ship hulls were brought in to help.
