It was originally known as Lavo or Lavapura, meaning "city of Lava" in reference to the ancient South Asian city of Lavapuri.
History
The city has a history dating back to the Dvaravati period more than 1,000 years ago. According to the Northern Chronicles, it was founded by King Kalavarnadish, who came from Taxila in north-west India in 648 CE. Lopburi, or Lavapura as it then was, was under the rule of the rising Angkor regime and became one of the most important centers in the Chao Phraya Basin from then on. Epigraphic evidence indicates that the dominant population of the city was Mon. The earliest confirmed occurrence of the name Lavapura is on silver coins inscribed "lava" on the obverse and "pura" on the reverse in a Pallava-derived script of the seventh or eighth century; several such coins were recovered in 1966 from a hoard found in an ancient jar in U Thong. Inscriptions say that Lopburi was incorporated into the administration structure of the Khmer Empire during the reign of Suryavarman I. Control of Lopburi gave the Khmer Empire access to trade going through the Kra Isthmus. There is some evidence the Khmer Empire, under Suryavarman II, fought against the Mons in the 12th century over suzerainty. Lopburi sent embassies to China in 1115 and 1155. Lopburi is described in Book III of Marco Polo's Travels, where it is called Locach. This came from the Chinese pronunciation of Lavo, "Lo-huk". The city is referred to as "Lo-ho" in chapter 20 of the History of Yuan, the official history of the Mongol, or Yuan Dynasty of China. Due to a scribal error in Book III of Marco Polo's travels treating of the route southward from Champa, where the name Java was substituted for Champa as the point of departure, Java Minor was 1,300 miles to the south of Java Major, instead of from Champa, on or near an extension of the Terra Australis. As explained by Sir Henry Yule, the editor of an English edition of Marco Polo's Travels: "Some geographers of the 16th century, following the old editions which carried the travellers south-east of Java to the land of Boeach, introduced in their maps a continent in that situation". After the foundation of the Ayutthaya Kingdom in the 14th century, Lopburi was a stronghold of Ayutthaya's rulers. It became the capital of the kingdom during the reign of King Narai the Great in the mid-17th century and the king resided there about eight months a year.
Bracelets and beads dated back 2700-3500 years were revealed at Ban Khok Charoen in 1966-1970.
Prehistoric human skeletons and clay jugs were found in Ban Tha Kae in 1979.
A Copper source was discovered in Khao Wong Phrachan in 1986-1994.

Today the city is best known for the thousands of crab-eating macaques that live in the middle of the city, especially around the Khmer temple, Prang Sam Yot and a Khmer shrine, Sarn Phra Karn. It is suspected that urban expansion caused the monkeys to adapt to city life. They are fed by the local people, especially during the Monkey Festival. This festival usually occurs on the last Sunday of November. The monkeys can be aggressive, are not afraid of humans, and often steal whatever items or food they can find from unwary visitors. Most of the hotels and guesthouses in Lopburi are "monkey-proofed", using screen wire, or by screwing the windows shut. In the city signs are posted reading: During the 2020 COVID-19 pandemic, lack of tourists prompted hungry monkeys to harass local residents.
