Bab al-Jabiya (Arabic: باب الجابية‎; Gate of the Water Trough) or the Gate of Jupiter is one of the eight ancient city-gates of Damascus, Syria. Bab al-Jabiya was the main entrance on the city's west side. The gate opens on Medhat Pasha Souq, which is the modern western half of the Street Called Straight, the Roman east-west artery (decumanus), which still connects it to Bab Sharqi (the Roman "Gate of the Sun").
