The main feature in (inside) a Protestant church is usually the cross. You may note that the Protestant churches favor a plain cross over a crucifix (the cross with the body of Jesus hanging on it). The plain cross emphasizes Christ's victory over sin and death while the crucifix emphasizes Christ's suffering on our behalf.
