The aim of here presented article is to analyse the role of Information and Communication Technologies (ICT) in a smart city concept and to evaluate their participation in the creation of smart cities. A smart city is an innovative concept which concerns a development of the modern cities. The idea of smart cities does not have one common definition. The disputes in the debates on smart city concern not only the issue of possibility of defining the metropolis as intelligent, but also the participation of new technologies in the development of the sustainable, bright cities. The reflections are theoretical and discuss, among others, different views of the smart city concept and approaches to new technologies within them. In the proper understanding of the smart city concept, as well as in the very processes of managing a smart city, new technologies play an important role and can help the city authorities cope with the challenges of modern times generated because of the growing number of city population.
