It consists of a large square display filled with paper flowers upon which the bodies rest. On the wall behind the bodies there is a mural of angels and a pair of large pillars stand in front of the shrine with a paper flower bouquets on each of them. There is also a circular ripple like pattern on the floor that resembles the Rinnegan between these two pillars.
When Konan exhausted herself during her fight with Obito the paper flowers began falling apart. After Obito found the shrine, he proceeded to absorb Nagato's body to his personal dimension and then teleported away, leaving Yahiko's body behind.
