In the lower part of the city is found the La Rosa lake, one of some 200 lakes in Mérida State. The other two principal rivers are the Mucujún and the Milla, which flow into the Chama and Albarregas. These two rivers run from one end of the city to the other. The most important river is the Chama, followed by the Albarregas, which cross the plain and divide it into two parts: the Banda Occidental (west bank) and the Banda Oriental (east bank). Mérida has four principal rivers and some smaller seasonal streams in the less urbanized parts of the city, these last ones have a significant water flow only in times of heavy precipitation. The old quarter of the city is on the alluvial plain known as Tatuy. The city is located in the center of the Venezuelan Andes, in a wide plain in the valley of the Chama River, between the Sierra Nevada de Mérida to the southeast and the Sierra La Culata to the northwest.

In 1622, Mérida became the capital of the Governorate of Mérida, whose chief official established his residence there. The city then came to be governed by the corregimiento of Tunja until 1607, when it became itself a corregimiento of the Audiencia of Santa Fe.
