The chapter shows the design, approach and results of an educational research project on the acquisition of geographic and spatial concepts together with heritage concepts for K-12. The project topic was the sixteenth-century watchtowers on the Mediterranean coast. A workshop and a fieldtrip were carried out. In the workshop, searches were done for information related to the location and construction of the watchtowers through online cartographical resources and reading of historical, literary and cartographical documentation. Fieldtrips were then made for observation and relationship among the watchtowers and the coastal landscape. From these activities, spatial problems were raised. Both problems are related to location, orientation and position of natural and cultural features and problems with the spatial interrelations between the watchtowers and the coastal landscape. The results offer some shortcomings in the training of students linked to the use of online maps, reading of cartographical documentation and the ability to represent simple cartographic schemes. However, students reinforced these shortcomings during the workshop and schools. The excitement with the applied use of online maps and the experience of the fieldtrip reinforced the acquisition of spatial concepts in relation to heritage. In this sense, heritage elements play an added value to the acquisition of geographical content and spatial geoskills.
