The Western Wall is the only part remaining of Solomon's Temple, built in the 10th century BC and destroyed twice. Praying here carries a lot of meaning for Jewish believers, who mumble hymns and insert prayers written on small pieces of paper between the bricks — every visitor is allowed to partake. The Temple was said to contain the Ark of the Covenant, a biblical golden chest. Moreover, Jesus reportedly visited the Temple as a child and left an impression on the wise men inside with his knowledge of the Bible. There are separate entrances for men and women leading to different parts of the wall. Friday evenings are particularly crowded, as Jewish people celebrate the arrival of Shabbat, the day of rest. Bar Mitzvah ceremonies take place in the morning on Monday, Thursday and Saturday: it's a great time to visit, as the place comes alive with Jewish song and dance.

Muslim Indian sepoys (soldiers) of the British East India Company’s Penang garrison built Masjid Kapitan Keling in 1801. It has been extensively restored and expanded in the two centuries since. Above the yellow domes and turrets of the mosque compound towers a tall minaret.

The next unmissable landmark is the Church of the Holy Sepulchre, built allegedly on Jesus's burial place. A historically accurate and possibly emotional way to reach the church is through the Via Dolorosa: this street of the Old City is said to have been walked by Jesus on his way to crucifixion. Every Friday, Roman Catholic believers walk the same street in a procession and stop at nine Stations: spots that commemorate significant events in Jesus's last hours. The last four Stations are located inside the church.
