Changhua Roundhouse
The Changhua Roundhouse was erected during Japan's rule of Taiwan in 1922 and is still operational today. It is believed to be Asia's last working roundhouse. There were initially six such buildings in Taiwan, but the other five had all been demolished by the mid-1990s.
This one was only preserved as a result of a public campaign. It now hosts diesel and electric trains rather than the stream engines for which it was originally designed, and it is also a tourist attraction. There are few facilities, basically, just a walkway and a viewing deck, and visitors must evade the occasional train that comes rumbling in. It's tucked away, but it's definitely worth a visit for a glimpse into Taiwan's railway history.
