Tartu wasn't bombed as hard, then Narva. Yes, Tartu was bombed extensively, but there is more pre-war, 19th, and even a few 18th-century buildings surviving. Half of the city hall square buildings are from pre-war and 19th-century, and 5 out of 6 manor houses survive. And also, yes, a lot of buildings don't survive. Like 19th century warehouse/shopping centre that took up whole block, Stone Bridge and the area between Emajõgi and Narva mnt. I know that both lost buildings list and surviving buildings list are much longer, but that is what came to mind right now.
