Ephesus is the largest and most complete of the existing ancient Greek and Roman ruins. Today, the excavated part of the site is only about 30% of the site. Nevertheless, Ephesus is still listed as a United Nations World Heritage Site. Because the site is too big, no matter where it is, it is impossible to take a panoramic view. Only a piece of ruin can be seen. Public toilets, imagine many people together, is it fun?
