The tetrapylon was used to mark the junction of two streets. The main street runs pretty much east to west and a smaller street that connects the forum with the Temple of Baal Shamin runs north-south. On a side note, one of the strangest experiences of my entire journey was on the day I caught the bus from Beirut to travel to the Syrian border. As we made our way up a small grade passing a landscape of barren scrub desert the buildings of the border crossing came into view. Lo and behold, set next to the various immigration and passport control halls is one of the biggest Dunkin´ Donut shops I´ve ever seen. For years now, Syria has had its name on America´s list of state sponsors of terrorism, but don´t let that throw you. Come on in and have an Apple Fritter or why not try a Jelly-filled?!
