Social media is commonly used by governments to disseminate information related to transparency and institutional promotion, but its potential for the dissemination of cultural resources is often overlooked. This research proposes a strategy for adopting social media to achieve cultural dissemination in the municipality of Lamas, Peru, which has tourism potential and has been awarded the “Best Tourism Villages” seal of the World Tourism Organisation. Methodologically, we propose a case study at a propositional exploratory level. We start by determining the current state of dissemination of tangible and intangible resources, as well as the practical use of social media, through a survey of 20 officials. The results reveal that crafts are the most widely disseminated tangible resource in the municipality (according to 55% of officials), and intangible resources are occasionally disseminated (50%). We also find that Facebook is the only digital channel used to disseminate cultural information. In this context, we formulate a strategy for adopting social media to improve cultural dissemination, which consists of six phases: (i) forming a work team, (ii) preparing a budget plan, (iii) strengthening capacities, (iv) taking inventory of cultural resources, (v) coordinating community interests and (vi) preparing a cultural dissemination plan. The findings can contribute to formulating public initiatives for the institutionalisation of social media in governments for the purposes of preserving, promoting and guaranteeing the accessibility of cultural heritage.
