The Rumeli Passage, a narrow alley on the right as you walk towards Galatasaray on İstiklal, popularly known as the TKP building, was also among Ragıp Pasha's real estate investments. Pasha actually built this place as a mansion in 1894. When the mansion life came to an end, it turned into a workplace. The passage, which bears traces of Italian architecture, had two gates, one opening to İstiklal and the other to Öğüt and Mayacı streets.
Block C in the passage, which consists of three blocks, turned into an art workshop after its exterior and interior were repaired. At the entrance, past the stalls selling accessories, elevators welcomed you to the building, which was home to such venues as Oyuncular Tiyatro Kahve, Monalisa and Rumeli, where the actors were regulars. Unfortunately, this passage also had its share in the recent hotel boom in Beyoğlu and closed down.
