Start your Tirchy adventure by visiting the Rock Fort Temple, a 7th-century Hindu temple built on a rock formation. This temple has three shrines dedicated to Lord Shiva, and it's a good opportunity to learn about Hinduism. The highlight of this temple is the steep climb to the top of the rock formation, which offers stunning views of the city. Be prepared to climb a lot of steps, and wear comfortable shoes. You can spend around 2 hours here.
After visiting the temple, head over to the St. Joseph's Church, which was built in the Gothic style in 1792. The high ceilings and stained glass windows are sure to impress you. Spend around 30-45 minutes here, admiring the architecture and stained glass windows.
Continue your spiritual journey by visiting the Sri Ranganathaswamy Temple, one of the largest temples in India and dedicated to Lord Vishnu. This temple is surrounded by a fort-like wall, and has 21 magnificent towers. The temple is famous for its intricate carvings, colourful paintings and breathtaking architecture. You can easily spend 2-3 hours here.
On your second day, start with a visit to the Government Museum Tiruchirapalli. The museum houses collections of bronze idols, stone sculptures, paintings, and artifacts from various periods of history. Additionally, it features sections on geology, anthropology, and natural history. This is an excellent opportunity to learn about South Indian history and culture, and you can spend around 2 hours here.
After visiting the museum, head over to Mukkombu, a popular picnic spot on the banks of the Kaveri River. Spend some time enjoying the serene atmosphere and beautiful scenery. Additionally, you can also take a boat ride to see the dam and the surrounding areas. You can spend around 2 hours here.
For travellers with more time, you can visit the Kallanai Dam, which is around an hour from Tirchy and is one of the oldest dams in the world.
