Medan as the capital of the province of Sumatera Utara and the third-largest city in Indonesia. The Medan metropolitan, as part of the constellation of the Mebidangro concept (Medan, Binjai, Deli Serdang and Karo), is closely linked to the nearby cities around it. The city gate of Medan has not yet succeeded in becoming a welcoming, attractive and educative city gate. This research is in the form of modeling based on consideration of location around the gate or cognitive mapping in qualitative descriptive with a phenomenology approach. The results show there is a definitive intersection between landmarks, nodes, and paths on edge. Variants of the city gate model do not have to be in the portal base form but can be in the form of symmetrical left and right monuments. This research is useful for study on the typology of city gates as well as elements of the locality that influence their formation. This study results will support and giving input on the review of policy towards the development of the concept Mebidangro Metropolitan spatial structure in 2029.
