Beigou Forbidden City 北溝故宮 is an obscure historic site hidden in the hills of Wufeng, Taichung. From 1949 to 1965 it was the provisional base of operations for the team of archivists, curators, scholars, and technicians overseeing the subset of the Palace Museum collection sent for safekeeping to Taiwan by the Kuomintang (KMT) in the later stages of the Chinese Civil War. Nowadays this collection is managed and displayed by the National Palace Museum 國立故宮博物院 (or simply Gùgōng 故宮 for short), situated in Taipei, and almost nothing remains of the facilities in Wufeng. The one exception is an underground vault constructed in 1953.

Here is yet another roadside curiosity in the deep south of Taiwan: a false tunnel on the coastal plains of Fangshan, Pingtung. It doesn’t cut through any mountainside nor is it built to withstand landslides. It’s just an 1,180 meter tunnel that trains pass through for no discernible reason. I first read about this on Michael Turton’s blog and later saw it on my first round-the-island bicycle tour. More recently I took a spin around the southern loop once more, and spent a little extra time examining this concrete oddity in an attempt to divine its purpose.

I found myself in the seedy port town of Keelung near the end of my round-the-island bicycle tour of Taiwan in 2013. Later on, after dinner was done, I went out wandering the labyrinth of night—and, on the far side of the railway line near Sānkēng Station 三坑車站 I noticed the entrance to a tunnel running beneath the hillside. Curious, I hunched down (the clearance is only around 175 cm) and made my way through. A minute later I emerged on the other side, somewhat disoriented, though I quickly regained my bearings.

Old Caoling Tunnel 舊草嶺隧道 was built in the 1920s to connect northern Taiwan with the eastern coast by rail. A new tunnel was built in the 1980s and the old tunnel was closed until 2008 when it reopened as a tourist-friendly bikeway. The main point of entry is Fúlóng 福隆, a beach town in New Taipei City about an hour outside of Taipei by train. Riding through the old tunnel makes for a great day trip from Taipei—as long as you don’t go on a weekend.
