Etymology
The name "Tiruvallur" is supposedly derived from the Tamil sentence "tiru evvull?" from "Tiru" (highness – a common prefix in South India for temple towns or cities) and "evvull" (where do I sleep?). Thus, Tiruvallur refers to a place/town where the god Veera Raghavar asked a saint for a place to sleep for a night.[3]
Tiruvallur was originally known as Tiru-evallur, which specifies the sleeping position of the Vishnu or "Perumal", in the Veeraraghava Temple of Tiruvallur. Later, people began to refer to it by names such as Trivellore and Tiruvallur. Today, Tiruvallur is well known, one of the reasons being the Veeraraghava Temple, where Amavasya (new moon) is considered an auspicious day for the lord and so for the people of the town.[4]

Geography
It is bounded on the north by Tirupati and Chittoor districts of Andhra Pradesh state, on the east by the Bay of Bengal, on the southeast by Chennai district, on the south by Kanchipuram districts, on the northwest by Vellore and on the west by Ranipet district. The coastal region of the district is mostly flat; but in the other parts it is undulating and even hilly in some places.
The northern taluks of the district like Ponneri, Uttukkottai, Gummidipundi etc. do not have much to offer from the scenic point of view. In the Tiruttani taluk, a number of hillocks are found scattered. The soil of the district is mostly sandy, mixed with soda or other alkali or stony. Rocks found in and near the surface are in detached masses. Hence, the soil can't be termed as very fertile. The soil found nearer the sea coast is of the inferior ericaceous type which is most suited for raising casuarinas plants. No mineral of any importance is available in the district. There are not many hills of any considerable height in this district. A few conical hills or ridges of small elevation exist like the St. Thomas Mount. Certain hillocks are found in Tiruttani. Most of the hills and hillocks are rocky and no verdant vegetation is seen in the slopes of these hills. The area under forests in this district is quite meager.
The average normal rainfall of the district is 1104 mm. Out of which 52% has been received during Northeast Monsoon period and 41% has been received during Southwest Monsoon period.
