English: The Thap Nhan or Nhan Tower, sometimes called the Swallow Tower, is a Champa era Hindu temple located on the Nhan hill in Tuy Hoa, near the Da Rang river. It sits on the top of a hill with sweeping views of the city, port and farmlands. The site and the temple has been variously dated to the about the 5th century, 9th century, and 11th century. Given the artwork and style similarities to the Po Nagar temple, it is more likely from the 11th century. The Thap Nhan temple illustrates one of seven styles of Hindu architecture that evolved in Vietnam between the 8th and 16th centuries. It is a uncommon example of a four storey brick temple with a square plan, about 25 meters high. The upper sections of the Nhan Tower are miniature replica of a classic Champa Hindu temple. The Nhan Tower temple was originally dedicated to Uma and Shiva (Parvati–Shiva).
