<p>In this article, a heritage assessment is made of the Francisco de Paula Santander Headquarters of the Boyacá College, located in the historic centre of the city of Tunja, which was declared a National Site of Cultural Interest (BIC) by Law 163 1959. For this, in the first instance, the conceptual development of cultural heritage was identified, to address the meaning of School Heritage. Second, the results of the assessment were presented, based on the historical, aesthetic and symbolic analysis (conceptual triad). As a result, it was possible to establish the applicability of the new concept of school patrimony to the Francisco de Paula Santander Headquarters. Likewise, with the patrimonial valuation carried out, the relevance of the school is evidenced as a national benchmark for the formation of society and patrimonial asset that contains the traces of different historical and architectural processes and a unique identity symbolism.</p>
