Formerly known as the Tainan Meteorological Station, it is a strange-looking building, also known as the pepper pipe. The middle pipe is "Wind Tower". Former workers climbed up the wind tower regularly to observe the clouds with their naked eyes. When the weather was good, they could see Shoushan, Kaohsiung, 30 or 40 kilometers away. Every day they took notes to monitor it. Now these original materials are displayed in the museum.
