This study explores ethnomathematics in the architectural elements of historical buildings in the Kota Lama Surabaya area, which contains rich geometric features from the colonial period. The research applies a qualitative method with an ethnographic approach to document and identify geometric patterns found in facades, windows, columns, roofs, and decorative ornaments. The analysis reveals that these architectural elements embody mathematical concepts such as symmetry, proportion, congruence, and geometric transformations. The findings show the presence of various plane figures including squares, rectangles, circles, triangles, and trapezoids and solid shapes such as cylinders, cones, and spheres. These elements serve structural and aesthetic purposes while reflecting philosophical meanings related to balance, continuity, stability, and harmony in colonial architectural design. The study demonstrates that ethnomathematics can bridge mathematics learning with local cultural heritage in a meaningful and contextual manner. The results contribute to the development of ethnomathematics in Indonesia and highlight the educational potential of historical architecture as a culturally relevant medium for teaching geometry.
