The city developed into a significant intellectual and artistic centre during this period. The city's golden age was during the mid-19th century under the reign of Maharaja Swathi Thirunal and Maharaja Ayilyam Thirunal. This era saw the establishment of the first English school (1834), the Observatory (1837), the General Hospital (1839), the Oriental Research Institute & Manuscripts Library and the University College (1873). The first mental hospital in the state was started during the same period. Sanskrit College, Ayurveda College, Law College and a second-grade college for women were started by Moolam Thirunal (1885–1924).
