 The first buildings in Hadar were constructed at the start of the 20th century . Hadar was Haifa 's cultural center and marketplace throughout the 1920s and into the 1980s , <unk> above and around the Haifa 's Arab neighborhoods . Today Hadar stretches from the port area near the bay , approximately halfway up Mount Carmel , around the German Colony , Wadi Nisnas and Wadi Salib . Hadar houses two commercial centers ( one in the port area , and one midway up the mountain ) surrounded by some of the city 's older neighborhoods .
