You might first learn about the Church of the Holy Sepulchre in Jerusalem when learning about pilgrimages.
It is quite an amazing place and is seen as really important by Christians because it is the site of Jesus’s crucifixion and burial. It has been in the news recently because it was closed due to Covid-19.
The Holy Sepulchre lies in the Christian Quarter of Jerusalem’s walled Old City. A church was first built there in the 4th century under Constantine the Great, the Roman emperor who converted to Christianity. The building is shared by Greek Orthodox, Armenian Orthodox and Roman Catholic churches and other Christians such as Copts, Ethiopian and Syrian Orthodox, also hold religious services there.
With the Jewish Passover festival starting on 8th April, Easter also right now, and Ramadan not too far off, religious communities have had to adapt their traditions to maintain social distancing.
