Mika Alas's House

The House of Mihailo Petrović, also known as Mika Alas's House, built in 1910, is a designated historic site of Belgrade located at 22 Kosančićev Venac in Belgrade, Serbia. Mathematician and scientist Mihailo Petrović (1868-1943) lived there, worked there, and died there. In the early 1900s, a Belgrade expression was, approximately, that "half of Serbian science lives at 22 Kosančićev Venac."

It was designed by architect Petar Bajalović, then an assistant professor at the Belgrade University.

The confluence of the Sava and Danube rivers can be seen from its balcony.
