The postcard itself (mailed in 2020 with two stamps and postmark) didn’t explain too much, and the writer was feeling a bit sad that day, so we did as we always do and went to Wikipedia to learn more.  Here is what they said, slightly edited:  “The Paper Dome (桃米紙教堂) is a temporary church building constructed using paper tubes as structural elements. It was designed by Shigeru Ban, Japanese architect, (and) built on September 17, 1995 to serve as a temporary church after the Great Hanshin earthquake.  The venue was not limited for use to religious worship but also used as a place for communal gatherings. However, when the church community planned to build a permanent building, the structure was donated to Taomi Village in Puli Township, Nantou County which had suffered the 921 earthquake in 1999. The deconstructed structure was shipped in 2006 to Taiwan, and is now one of the top tourist attractions in that area.”  Grade: 1
