This paper describes a research project that explored the use of mobile augmented reality combined with outdoor education in a Swedish primary school. Special attention was paid to mobile augmented reality (AR). Project documentation and communication were reviewed, three iterations of design and usability evaluations of the Minnesmark mobile AR platform was made. Observations and interviews were held with teachers and students. The results describe early experiments, and both the opportunities and challenges that faced the participating teachers. The opportunities included connecting the outdoor learning environment and the indoor learning environment, directing the students' focus, posing questions and affording actions, rendering symbols and timelines visible, providing a point of entry to the context and the narrative, and facilitating conceptualization. Challenges concerned how to make pedagogical use of the landscape, producing or choosing content, structuring processes, setting up student groups, and aligning activities and content with learning objectives. It is concluded that the teachers and the students used the mobile augmented reality to make places in the local environment, outside the classroom, the starting point to increase the authenticity of the teaching.
