Taiwan

I received this postcard today...from Taiwan.

According to the sender, this postcard is a painting of a place of historic interest in Tainan.  However, there is no mention of the name of the place.  I haven't been able to figure it out.  Do you know?

I did learn some things about Tainan.  :)

• Tainan is officially known as Tainan City.
• Tainan is a city in southern Taiwan.
• Tainan is the oldest city in Taiwan.
• Tainan faces the Taiwan Strait in the west and south.
• Tainan formerly was named Tayouan, which has been claimed to be the origin of the name "Taiwan."
• Tainan is a cultural capital of Taiwan, for its rich folk cultures.
