神子畑鋳鉄橋

This is a Japanese heritage mine that was discovered accidentally on the way from Sakai to Asago. If you run on a mountain path, it will come out suddenly. ️ It might be a little scary if you go after the evening It is a Japanese heritage, but it is not developed as a tourist. Go once and taste the power of this place ?

I visited for the first time today. The surrounding roads are closed due to the typhoon! It is a good place to fix this right away!鉄 From such a place, iron ore comes out? Well, I think it's a bit complicated, but in the blue sky there's a cloud and a deep blue sky spreads out! I am relaxed today. The cultural heritage was badly damaged and only sad thoughts came out, right? I felt like a legacy that was betrayed of the past, eternal desires.

Because it was on Google MAP ... It's just a whim ? Recently Corona If you think of a less popular place ... View photos on Google MAP, I want to see the real thing and go there. Google MAP post photos and search It is useful as a car navigation system. By the way ... this Mikobata Cast Iron Bridge It is an important cultural property of the country.

This place is also good. If you think it's a little bigger, it's surprisingly small. I will miss it if I run.

The Kamikohata mine was rediscovered in 1891, and after the full-scale opening of the mine in 1884, a road was needed to transport the ore. Was built and many bridges were built. It is said that this construction started in 1887 and was a major construction with a total construction cost of 40,000 yen for two years until 1887. The Kamikohata Cast Iron Bridge was built when this Bashamichi crossed the Kamikohata River. In addition, although all the construction work is designed and constructed by Japanese, it is largely due to the result of the technical guidance of the French engineers who developed the Ikuno mine. At that time, five bridges with different structures were built on the carriage road between Kamikohata and Ikuno, but the existing ones are Kamikohata Cast Iron Bridge (a series of arch bridges with a bridge length of 16 m) and Habuchi Cast Iron Bridge (Bridge). There are only two 18m long double arch bridges), both of which retain the appearance of a beautiful Western-style bridge. The Kamikohata cast iron bridge is said to be the third oldest existing iron bridge in Japan, but the first Shinsaibashi in Osaka (Meiji 6) is made of wrought iron, and the second is the bullet bridge in Tokyo (Meiji 11). Is a mixed wrought and cast. Therefore, this cast iron bridge will be the oldest all-cast iron bridge in Japan. In particular, the Kamikohata cast iron bridge is a transitional period in the history of Japanese bridges from the viewpoint of materials that have evolved from wooden bridges and stone bridges to bricks, and then to cast iron, wrought iron, and steel. It is historically valuable in terms of the stage, and it is the bridge itself as a very valuable cultural property with dynamic beauty.

I went there because it came out at a famous place, but it looks like a normal bridge. But if you know the history, you will be convinced. All are cast iron. Since it is the 16th year of the Meiji era, it is an industrial heritage site in modern Japan. Worth a look

It is said to be the oldest cast iron bridge in Japan. There is a monument and a parking lot right next to it, so it's easy to visit. I didn't know its existence until I happened to be told by a local person when I stopped by the site of the Kamikohata concentrator, which became famous on SNS recently. On the way from the national highway to the site of the concentrator, there was certainly a nobori, but you wouldn't notice it unless you told it. I think I should make it stand out a little more. If you don't tell me, it's so good that you can't tell that such precious things were left until this time, and you can walk around normally. It doesn't matter when I cross it, but I was personally impressed just by being able to touch important cultural properties. I think it is a wonderful heritage where you can feel the breath of civilization.

It is the oldest existing all-cast iron bridge in Japan. [Explanation below] The bridge is an arch bridge made of cast iron that spans the Mikobata River that flows through the Sano district of Asago City, Hyogo Prefecture. In order to transport the ore mined at the Mikobata Mine to the Ikuno Smelter in Ikuno, it took two years from 1883 to construct an ore transport road of about 16km. It is one of the iron bridges built for guide cars and ox carts (railroad tracks for minecarts such as railroad carriages were laid in 1891) as part of the construction of the transportation route. It is the oldest cast metal product in Japan, and it is said that it was made at Yokosuka Shipyards and shipped to Kazuma by sea. Was done. This work was constructed by the Ministry of Industry of the Meiji government at a total construction cost of 40,000 yen. There were four other bridges, but there are only two existing, the Habuchi Cast Iron Bridge (two arch bridges with L = 18m) and the Kamikohata Cast Iron Bridge. Along with Hachiman Bridge (formerly Dansho Bridge) in Tokyo, it was designated as a national important cultural property on June 27, 1977 for the first time as a modern bridge. Due to its deterioration, it was repaired in 1982 for the purpose of permanent preservation over a year. It was certified as a Heritage of Industrial Modernization in 2007. In 2017, it was also certified as a Japanese heritage site. This bridge is the oldest existing all-cast iron bridge in Japan. There is a parking lot near the bridge, and explanation boards for the bridge and mines are also maintained. There is also a promenade nearby and you can walk on the bridge. chronology November 1878 (Meiji 11) --Rediscovering silver veins at Kamikohata Mine 1885 (Meiji 18) -Construction of the mining road between Kamikohata and Ikuno, which started in 1883 (Meiji 16), is completed. 1917 (Taisho 6) --Kamikohata Mine closed 1919 (Taisho 8) --The Kamikohata concentrator is built on the site of the Kamikohata mine.
