The Lourdes Grotto is another Catholic shrine and place of meditation in Baguio. It is located on a high hill in the western part of the city where you will find the image of the Lady of Lourdes.
The grotto is a favorite pilgrimage site during Holy Week most especially during Holy Thursday and Good Friday. Access to the top of the grotto could be made by climbing the 252 steps or by driving a light vehicle through a winding, narrow and steep asphalt-paved road. Devotees who go up to the grotto to pray usually light up a candle at an altar below the image. There are also vendors at the shrine who are willing to light up a candle for you and say a prayer for whatever personal intentions you might have.
As it is in many other similar shrines, the grotto was constructed to commemorate the numerous visions of the Virgin Mary by a 14-year old French girl named Bernadette Soubirous. This happened in 1858 from February 11 to July 16 in the town of Lourdes which is in southwestern France. The visions were declared authentic by the Pope in 1862 and this also led to the authorization of the cult of Our Lady of Lourdes.
