'''Ariyalur''' ({{IPA|ta|aɾijaluːɾ|lang}}) is a [[town]] and district headquarters of [[Ariyalur district]] in the [[South India]]n state of [[Tamil Nadu]] and is rich in limestone, surrounded with seven cement factories and two sugar factories. The town is located at a distance of {{convert|310|km|abbr=on}} from the state capital [[Chennai]].

Ariyalur was a part of the erstwhile [[Trichinopoly District]] until India's independence in 1947 and [[Tiruchirappalli district]] until 1995, Perambalur district until 2007 and subsequently a part of the newly formed Ariyalur district. The town is a part of the fertile [[Cauvery Delta]] and the major profession in the town is agriculture.

Ariyalur is administered by a municipality established in 1994. As of 2011, the municipality covered an area of {{convert|7.62|km2|mi2|abbr=on}} and had a population of 28,902. Ariyalur comes under the [[Ariyalur (State Assembly Constituency)|Ariyalur assembly]] constituency which elects a member to the [[Tamil Nadu Legislative Assembly]] once every five years and it is a part of the [[Chidambaram (Lok Sabha constituency)|Chidambaram constituency]] which elects its [[Member of Parliament]] (MP) once in five years. Roadways are the major mode of transportation to the town and it also has rail connectivity which acts as a main station after Tiruchirappalli junction. The nearest seaport is [[Karaikal port]], located {{convert|95|km|mi|abbr=on}} away, while the nearest airport is the [[Tiruchirappalli International Airport]], located {{convert|76|km|mi|abbr=on}} away from the town.

==History==
Ariyalur town has a rich historical legacy, primarily associated with the later phases of the Chola dynasty. During the Chola period, the region was governed by the Paluvettaraiyar chiefs, who served as feudatories under Chola kings from Aditya I to Rajendra I. Their capital was Melapaluvur, located near present-day Ariyalur. This area was known for its administrative importance and proximity to Gangaikonda Cholapuram, the imperial capital established by Rajendra Chola I.

Following the decline of the Cholas, Ariyalur came under the rule of the Vijayanagara Empire and later the Nayaks of Madurai. The Vijayanagara Nayak rulers contributed to the construction of several temples in and around the town, most notably the Kothandaramar Temple, which reflects the architectural style of the period.

In the mid-eighteenth century, Ariyalur was one of the two important palayams (feudal estates) under the control of local Poligars. In 1741, when the Marathas invaded Tiruchirappalli, Chanda Sahib was captured. After his release in 1748, he became embroiled in a power struggle with Anwaruddin Khan and his son Muhammad Ali Khan Wallajah for control of the Carnatic region. During this conflict, the Nawab of Arcot accused the Poligars of Ariyalur and Udayarpalayam of defaulting on tribute payments and disloyalty. With British support, forces under Umdat-ul-Umara and Donald Campbell invaded Ariyalur in January 1765 and captured the town. The Poligar of Ariyalur fled to Tharangambadi, then a Danish settlement, marking the end of local autonomy in the area.

After the fall of the Poligars, Ariyalur came under the administrative control of the Nawab of Arcot, and subsequently the British East India Company following the defeat of Tipu Sultan in 1799. By 1801, the Tiruchirappalli district was reorganized under British administration, and Ariyalur was incorporated into it as a prominent regional centre.

During the British period, Ariyalur developed as a local administrative hub and a centre for limestone quarrying, which later evolved into the cement industry that continues to define the town’s economy today. Post-independence, Ariyalur became the headquarters of the newly formed Ariyalur district in 2001. The town has since grown as an industrial, educational, and archaeological centre, located close to the UNESCO World Heritage candidate site of Gangaikonda Cholapuram.

==Geography==
Ariyalur is located in the central part of Tamil Nadu, India, at a latitude of 11.14°N and a longitude of 79.08°E. The town lies on the plains of the Kaveri River delta, although it is not directly situated on the river. It has an average elevation of 90 meters (295 feet) above sea level, with relatively flat terrain interspersed with small hillocks.

The region experiences a tropical climate, characterized by hot summers from March to June, a southwest monsoon from June to September, and a northeast monsoon from October to December. Average annual rainfall is around 800–1,000 mm, supporting both agriculture and groundwater recharge. The climate is generally dry outside the monsoon periods, and temperatures can rise above 40 °C in peak summer.

Ariyalur is rich in mineral resources, particularly limestone, which has significantly influenced its topography and economy. The sedimentary rock formations in the area date back to the Cretaceous period, and extensive fossil deposits have been discovered in and around the town. These geological features have made Ariyalur an important site for paleontological studies, contributing to its recognition as a fossil-bearing region.

The town is well-connected by road and rail, with National Highway NH-136 passing nearby and the Ariyalur railway station serving as part of the Chennai–Tiruchirappalli line. Its central location in Tamil Nadu allows easy access to neighboring districts such as Thanjavur, Tiruchirappalli, Cuddalore, Perambalur, Tiruvarur and Nagapattinam.

===Climate===
Ariyalur has a [[semi-arid climate#Hot semi-arid climates|hot semi-arid climate]] ([[Köppen climate classification|Köppen]] ''BSh''). Temperatures are hot to sweltering throughout the year, and especially unpleasant during the wet season under the [[northeast monsoon]] from October to December. The [[rain shadow]] of the [[Western Ghats]] means that Ariyalur receives very limited rainfall during the southwest monsoon, but the city is likewise too far inland to receive sufficient northeast monsoon rainfall to be a [[tropical wet and dry climate]].

==Economy==
Ariyalur's economy is predominantly driven by the cement industry, owing to its rich deposits of limestone and proximity to lignite reserves. The town's industrial landscape is further diversified by agriculture, particularly the cultivation of sugarcane and cashew, and the presence of a private sugar factory near Keelapalur with a crushing capacity of 3,000 tonnes per day.

=== Cement Industry ===
The cement industry in Ariyalur has a storied history, beginning with the establishment of the Tamil Nadu Cements Corporation Limited (TANCEM) in 1976. TANCEM took over the Alangulam Cement Plant from TIDCO and set up an additional plant in Ariyalur in 1979. This move marked the commencement of organized cement production in the region. The Ariyalur Cement Works primarily supplies cement to government departments and has a wide network of stockists for open market sales in the central and northern districts of Tamil Nadu and northern Kerala.
