This paper presents Croatian lighthouses as cultural and historical monuments. The goal of the paper is to present the commercialization of Croatian lighthouses through the project Stone Lights as a concrete example of good practice in promoting Croatian tourism and creating of a new Croatian brand. This paper aims to show how past and present fully complement each other. Regardless of the advances in technology and changes in the sense of functioning of modern navigational aids, lighthouses as cultural-historical monuments will never lose their value. Still, the author feels the need to emphasise that it would truly be unsustainable to invest into the reconstruction of the lighthouse buildings because nobody lives in most of them and for the vast majority they are automated. In this sense, the project Stone Lights offers a sustainable concept of maintenance and investment into lighthouse buildings. Its dual role manifests itself in the fact that recuperating of lighthouses at the same time greatly improves what Croatian tourism has to offer in general. There are very few tourist destinations in the world that offer accommodation in lighthouses. Therefore, it can be said that Croatia, i.e. the company Plovput, through its project Stone Lights made the right move aimingto improve Croatian tourism. The paper develops in three basic sections. The introduction describes the subject of the paper, presents the hypothesis, the goals and the purpose of the research. The first part of the paper concentrates on the lighthouses and their history. It also presents a comparison between the old lighthouses and the ones operating today. The second part of the paper presents lighthouses as cultural and historical monuments and presents how recuperating of lighthouse buildings through commercial activitiescan be achieved. The third part deals individually with each lighthouse actively involved in Croatian tourism.
