Wiki Loves Monuments (WLM) is an annual international photographic competition held during the month of September, organised worldwide by Wikipedia community members with the help of local Wikimedia affiliates across the globe. Participants take pictures of local historical monuments and heritage sites in their region, and upload them to Wikimedia Commons. The aim of event is to highlight the heritage sites of the participating countries with the goal to encourage people to capture pictures of these monuments, and to put them under a free licence which can then be re-used not only in Wikipedia but everywhere by everyone.
