Landmarks have always been used in directions due to the lack of street signs and building numbers in Beirut. "50 meters after the pothole", "right next to the chestnut tree", or "where that restaurant used to be" are regularly used even though that restaurant closed before you were born.
These days, however, directions have gotten much easier. You see the huge picture of Saad Hariri with his dad hovering over him? I'm in the third building to the right. There's that building with the whole side covered with a humongous Hassan Nasrallah, he's even larger than the crowd at the downtown rally. The big poster with the much younger yet no less bald Samir Geagea points you in the right direction. At the end of the road you'll see a Large picture of Pierre Gemayyel turn right; your right, his left. Don't worry the power is out but the general and his bright orange mural will illuminate the way. And just in case you get lost getting to Nabih Berri's residence, there he welcomes you with a slick smile and even slicker Ray Bans.
You can't miss it.
