There are some nice examples of impressive Ottoman architecture in the Balkans such as Mostar bridge in Bosnia.
I want to add some other examples from Albanian city of Berat.
Let’s start with the bridge. It was build in 1770 but it is still in a great state so that sometimes there are even heavy tracks going over it :
Again from the city of Berat there is Mangalem neighborhood :
For this Berat is also called the city of “Thousand over thousand windows” .
Part of the reconstruction of the 2400 years old castle of Berat is also of ottoman period :
And The inner part of it :
Some remains of an old moschea
Other architectures of minor interests are the bridge in village of Vokopole, Berat you can see below. To me it seems incredibly similar to the Mostar bridge in Bosnia.
Other architectures worth to mention are the following moschea build between 1500 and 1650 also called the
Beqar Moschea
The inside part of it.
About this I read very recently this Why Major Art Museums Are Going Gaga For Islamic Art (http://www.businessinsider.com/the-louvres-and-the-mets-islamic-art-collections-bridge-the-divide-2012-10?IR=T) on business insider.
Disclaimer: Berat is the city I was born in (and proud of :-) ) so that’s why I wrote only about othoman period architeture you find there. Sorry for that ;-)
Later on in 2008 UNESCO decided to inscribe Berat in the **UNESCO World Heritage List **so maybe my opinion is not that biased.
