Even after the park opened to the public, construction continued on park facilities including the Huxin Pavilion, which celebrated its 100th birthday in 2008. It was opened in 1908 to celebrate the completion of the Keelung-Kaohsiung train link, and Taichung's central location made it the perfect location for such a commemorative icon.
開園之後，園內的設施和建築物才陸續完成，其中剛剛歡度百歲生日的「湖心亭」，興建西元 1908 年，當年為了慶祝台灣縱貫鐵路全線開通，日本政府在位處縱貫線中心點的台中，舉辦了「台灣縱貫鐵路全通式」，湖心亭正是這項鐵路盛典的「紀念建築物」。
