You can find out about the history of Patiala when you stop by Gurudwara Charan Kamal Sahib. Wander the gardens and parks while you're in the area.
Gurdwara shri Dukh Nivaran Sahib is just one of the landmarks located 1.6 mi (2.6 km) from central Patiala, so you might want to stop by for a few pics during your trip.
