Why turks didn’t leave many signs of their culture in Greece?

There is no doubt that the Ottoman empire was a great
one and not just a slaughter for conquest. A question
that raised quite naturally to me is, why the period of
Turkish domination over the peninsula, which lasted
more than 400 years, is considered a static and
retrograded period? I mean, with a new conquest there
is a positive impact to the economy and the peninsula
was (is) as strategic point of military and trading
advantage. Why there are no ruins (except very few
temples) or cultural evidence of an empire? To be more
precise, take Sicily for example. There are evidence of
greek culture all over the island plus the very
beautiful city of Palermo is a jewel of Arab dominance
(831 DC) . I am not saying that there was no cultural
mixing and maybe there were big monuments that I ignore
or worse have been destroyed. I am open to any
correction or help , this is my first post here so
please be comprehensive.
