Hundreds of years before the street was marked today, the route of Tkalčićeva Street was the channel of the Medveščak River. It is called Crikvenik. From the Middle Ages it was the center of many industry. The most important of these are the water mills industry. The water mills caused the development of Zagreb and led to the construction of the first textile plants, soap, paper and alcoholic beverages, and later also to the leather industry. The water mills were often the subject of fierce arguments between two twin cities, Kaptol and Gradec. A peace treaty of 1392 forbade the construction of new water mills along the channel between the southern end of Medvedgradska Street and Banjalacic Square, leaving only two Mills within the city. The two mills were owned by the Sistercian monastery. However, they were destroyed during the covering of the streambed in 1898. Although both sides of the stream were previously inhabited, the cover of the stream in 1898 created a whole street, called Ulica Potok (River Street). In the middle of the 20th century it was paved with asphalt. River Street quickly became a small business street and shops and the leather industry stopped working in 1938. In 1913, Ulica Potok's name changed to Tkalčićeva Street in honor of the 19th century Croatian historian Ivan Tkalčić. Translated with Google Translate
