The National Museum of Taiwanese History (國立臺灣歷史博物館) is situated beside the historically significant Taijiang Lagoon (台江內海). Since the 17th Century, Taijiang Lagoon has attracted traders from both east and west, but due to environmental changes has gradually silted up. The historical museum was established here to give visitors a sense of the transformation of sea into land over time. All parts of the museum, inside and out, are worth savoring. Surrounding the museum are lots of public art installations, including a large moving installation made from oars, symbolizing the ambitious spirit of the area's forebears when they came to Annan District (安南區). In addition, the always bright and flashing Thanksgiving Tree with its stainless steel exterior has become a place at which live to take photos and check in on Facebook. The inside is a wealth of historical, cultural and natural exhibits. Based on a mixture of historical fact and imagination the display rooms allow visitors to explore a veritable treasure trove of Taiwanese history.
