December 4th, Buddhism
I was visiting in Rupandehi District of Nepal. While I was there, I visited the temple of Lumbini, the place where Siddhartha Gautama (the god Buddha) was born. I saw a large, white, and rectangular temple with a body of water in front of it. There are also trees and paths around the site, and from one side there is a path leading up to the temple. This is a sacred garden and a sacred pool that is used for praying. For Buddhists, this may be considered the most sacred place because it is where Queen Maya Devi gave birth to Buddha. This temple is thought to be the earliest evidence of Buddhist structures and the first archaeological evidence of Buddha's life, dating all the way back to before 550 BCE.
December 7th, Hinduism
I was visiting in India when I came across the Jagannath temple of Puri. This temple has a main wooden temple with a bunch of smaller wooden temples surrounding it. Jagannath is sacred because it is dedicated to lord Jagannath. This is sacred because the Jagannath temple is also apart of the Char Dham, which is an important Hindu pilgrimage circuit in the Indian Himalayas. Traditionally, the trip starts at the eastern end from Puri, proceeding in clockwise direction. The temple is one of the holiest Hindu Char Dham sites.
December 11th, Christianity
I was visiting in Jerusalem when I came across the Church of the Holy Sepulchre, one of the most sacred places of Christianity. I saw a very large and old Church with dome like pieces at the top along with a giant cross. This is sacred because the site of the Church of the Holy Sepulchre in Jerusalem is identified as the place both of the crucifixion and the tomb of Jesus of Nazareth. The church has also been a major pilgrimage center for Christians all around the world.
December 13th, Judaism
I was visiting in Israel when I went to Jerusalem. When I went there, I saw a lot of old architecture, including a lot of synagogues. I saw the Kfar Bar'am, a very famous synagogue. It was broken down and all that is left is the bottom structure and some pillars. This is because it was badly damaged in the Galilee earthquake of 1837. This specific synagogue is sacred to the religion of Judaism because it was believed that in the 12th century to contain the tombs of Barak, the prophet Obadiah and Queen Esther. The Jews of Safed would come together around these shrines each year on Purim, which means to eat, drink and rejoice.
December 16th, Islam
I was visiting in Mecca, Saudi Arabia when I came across the famous Masjid al-Haram, or the grand Mosque of Mecca. This is the largest mosque in the world, and it surrounds the holiest place in their religion, Kaaba. There was a big black box in the middle of many people. I saw a huge mosque, which I later found out was 3,841,000 sq ft, and can hold up to 820,000 worshipers during the Hajj period. This place is very sacred to the religion of Islam because more than 2 million worshipers gather to pray during Eid prayers, and the Kaaba is considered the most sacred thing in their religion. Most muslims turn there to pray every day.
