Additionally, there are the Institute of Philosophy and Social Sciences, the Institute of History, the College of Law Studies, the Valongo Observatory, the School of Music, the Residence of College Students and the National Museum (53 276 40 m2). Among the isolated health buildings there are the Maternity School, the São Francisco School-Hospital and the Anna Nery Nursery Schools. The UFRJ possesses additional campuses in Rio de Janeiro's Chile Avenue (8 550 m2), in the cities of Macaé and Duque de Caxias (149 869,18 m2), Jacarepaguá (10 000 m2), Arraial do Cabo and in Santa Teresa (a 1.5 million m2 research-only wildlife reserve). Structure UFRJ can be divided into six university centers plus the "Escritório Técnico da Universidade" (University Technical Department), the "Fórum da Ciência e Cultura" (Forum of Science and Culture, FCC) and the University City Hall. Each center is made of dozens of units and supplementary organs responsible for education, research and extension in their respective areas of knowledge. University Centers Center of Health Sciences (CCS): the university's largest, involved in activities and research related to biosciences. As a whole, it gathers ten units and fourteen supplementary organs: three hospitals, three "nuclei" (headquarters), two schools, three colleges and thirteen institutes. Activities are developed mostly at CCS's main building at College City, but there are also units at Praia Vermelha, in downtown Rio, in Macaé and in Xerém. Center of Technology (CT): the university's second largest center, it manages two sprawling engineering schools and two high-tech research institutes, all located at College City. The CT also controls two business incubators and one foundation focused at technological studies. These units were all previous to the center's foundation, each with a unique history, and their performance is crucial to the national technological environment, given that together they form one of the country's most influential tech-poles. Center of Mathematical and Natural Sciences (CCMN): originated from the traditional and influential National School of Philosophy, it is made of five institutes and one observatory. Its main infrastructure is located at College City. The Institute of Chemistry and the Institute of Physics are located at Center of Technology's Block A and the Institute of Mathematics, at its Block C, but both are units of CCMN. The Valongo
