Theatre of Pompey, dedicated in 55 BCE (construction began in 61 BCE), built on Campus Martius (gets around restrictions), Largo di Torre Argentina (area with 4 shrines/temples), 1st permanent theatre, variation on Greek theatre, gives it other elements to make it more socially acceptable (building with meeting place for senators, shrine on top dedicated to Venus Victrix - can claim he built a shrine not a theatre), large garden with water features in the center, decorative elements things Pompey brings back from war
