Lourdes is a lovely place especially for Catholic devotees. An apparition of Our Lady of Lourdes was said to appear to St. Bernadette then believers started to visit this place. The Sanctuary of Our Lady of Lourdes is a beautiful site. It is nearby the train station and could easily be walked by the elders. This place is very serene and holy. Mind the clothes that you will wear. You could also ask for Confession from the priest at the bottom of the church. Around the church, they can dip you in cold water to wash away your sins. The water from the fountain is said to be holy. It is free, just bring a water bottle.
