As part of my commitment to blogging on Taiwan's museums, I blogged the other day on the National Taiwan Museum. I should mention that I've also got a web page on the 9/21 Earthquake museum in Wufeng. This is a very interesting museum, built on the grounds of a school destroyed in the quake.
If you are in the area, it is worth taking an hour to explore the place. The ruined buildings are awesome, and the exhibits are professional. The standard of English is good, though not native speaker. There are concerts and other activities on the weekends, and a wide expanse of grass.
