Tiruchirappalli also called Tiruchi or Trichy is an ancient city in India's southern Tamil Nadu state. The Kaveri and Kollidam rivers flow around Srirangam Island, which is known for sacred Hindu sites Sri Ranganathaswamy Temple, with intricately carved gopurams, and Jambukeswarar-Akilandeswari Temple, dedicated to the god Shiva. The Rock Fort Temple complex towers over the city center.
Close by, Our Lady of Lourdes Church is a replica of a Gothic-style French church, with brightly colored stained-glass windows. Farther south, the Rail Museum displays photographs and artifacts from the 19th century, when Tiruchirappalli was the headquarters of a British Raj-era railway network. The Anna Science Centre Planetarium features interactive exhibits exploring biodiversity, gravity and sustainable energy, plus an herb garden and a cinema with 3D films. East of the city, the Kallanai Dam, originally built during the Chola dynasty in the 2nd century A.D, diverts the waters of the Kaveri River.
