How to Love City Not Just in Words photo exhibition opened in Koltso in Kazan on 19 April. The exposition tells about Tom Sawyer Fest volunteer movement for conservation of the historical environment. The photos show residential wooden houses of Kazan before the volunteers' help and after the Tom Sawyer Fest participants' façade improvement. The ''portraits'' of the seven houses that the volunteers will update this year are also here. An excursion to Kazan's centre took place after the photo exhibition opened.
