The center was inhabited since pre-Roman times, as evidenced by the discovery of a necropolis dating from the ninth century BC Certainly the current town insists on the necropolis of the village built in the age of iron and in the next period called "Orientalizing", that is, between the ninth and sixth centuries BC The first inhabitants of the village were the Opici who tilled the land and introduced the first and most profitable crops: cereals, vines etc.. These were replaced by the Etruscans, the Samnites and Romans. In Samnite, the fertile land irrigated by Sarno saw the installation of the first country villas, real farms. The great earthquake of 62 and the subsequent eruption of Vesuvius on 24 August 79 AD that buried part of the countryside under a thick layer of lapilli and ash, brought death and desolation, forcing the population to flee, abandoning the fertile lands. Thus began the town over a period of darkness. In the third and fourth century life returned, the rustic villas resumed their activities. These late-imperial villas were equipped with a pars Dominica, direct possession of the owner and a pars massaricia assigned to settlers-serfs. The start of a real recovery occurred in 1100, thanks to the work of the Benedictines; macchiosi land were cleared and cultivated the wetlands were made and improved existing crops. The City of Striano was hit in 1707 by the fall of abundant pyroclastic rocks along the towns of Pompeii, Torre del Greek and Boscotrecase. Damage to crops, hundreds injured. On 8 December 1806, the Village Taverna Penta, became independent from Striano, becoming so common Poggiomarino. The municipality did not remain alien or the revolutionary movements of the nineteenth century, even the two world wars. With the advent of the Republic, along with traditional agriculture, developed the craft, trade and small industries.
The name of the municipality there are conflicting opinions: Traditionally it was thought that it came from Istra, wrong place of origin of San Severino, the patron saint of the town. Recently, through studies and research, it was shown that the name derives from exactly the characteristic configuration of the land called strianesi stigati, and how to work them.
