Due to its vantage location, Pen developed as a port city (present day Antora port was commonly referred as "Pen Port"), with trade links as far as Egypt. It had a very prosperous marketplace where exchange of goods to and from deccan took place.
The Kolaba District Gazettee gives Pen's history as follows
|“||In historical times Pen was under rule of the Silaharas of Shri Sthanak (Thana) from 9th to the 12th Century and subsequently it passed under the control of the Yadavas. When Shayastakhan was sent against Sivaji, a detachment of the Moghal army had been kept at Pen but it was subsequently routed by him. Parvatibai, the wife of Sadasivrav Bhau, the hero of Panipat,. In 1819 the easy communication with Bombay and with the Deccan by the Bor pass made Pen an important centre. Its chief prosperity lay in its salt beds. There was a considerable export of rice to Bombay. A number of carved stones about the town appear to belong to an unusually large temple of about the thirteenth or fourteenth century.||”|
During the period of shilahar kings, many temples of goddesses were built, including Jagdumba of Vashi. In the period of Chalukyas, grand temples of shiva, like rameshwar(रामेश्वर), pataneshwar(पाटणेश्वर), goteshwar(गोटेश्वर) and vyaghreshwar(व्याघ्रेश्वर)were constructed 
In shivaji era, shayistekhan's raid on deccan led to major fights in Pen Taluka between moghals and marathas. Initially moghal army led by sardar Taherkhan occupied Pen's fort of Mahalmeera and looted surrounding villages, which included desecration of grand temple of goteshwar. Shivaji's army fought back with vengeance. They defeated Kartalabkhan in nearby Umbarkhind and officer Balakhi, near Ratangad. Stronghold of Mahalmeera was also taken back on 27th Feb 1662 and the following day, after a valiant struggle, Pen's Bastion (presently, the site of Tehsil office) was secured by Shivaji's army. In this conquest, Sardar Vaghoji Tupe fought mesmerizing battle against equally skillful moghal officer but at the crucial moment, Tupe dealt a decisive blow which killed the officer and ensured Maratha victory. Vaghoji was also critically injured and died soon afterwards. Shivaji Maharaj himself visited Pen on two occasions, on 6 August 1668 and 11 May 1674.

Development and Economy
People in the Pen city are employed in various sectors such as trade/business, education, banking, industries, services, papad making (women's' co-operatives) and most importantly, idol making!
Most villagers are dependent for livelihood on Paddy farming in monsoon. Various vegetables are also grown as by-products, especially in eastern part of the county.
Industrial belt in western part of the county is causing a major problem of pollution in surrounding rural areas, creating health problems and reducing crop yields. Reliance Industries was promoting a Maha Mumbai Special Economic Zone, located around the town. A study conducted by Citizen's Research Collective on SEZ has called the Maha Mumbai Special Eeconomic Zone a Special Exploitation Zone Land owners resisted the purchase of their land for the purpose and following a historic referendum on the issue, SEZ was cancelled.  Land prices are soaring and economy is growing rapidly but there are some serious concerns about uneven and unjust development.

From historic times, city of Pen was center of education and culture in konkan region. In fact, Lokmanya Tilak used to call it "कोकणचे पुणे"(Pune of Konkan) due to progressive mindset of Penkars and their love of knowledge. There were at least two school of vedas(वेदशाळा) in Datar Ali area of Pen city, one of them in Sahasrabuddhe family. Pundits from all over Maharashtra used to come to Pen to make copies of rare ancient books(पोथी). Sages of Pen were so superior intellectually, that they defeated sages who accompanied shankarachrya of Kashi, in debates on Religious studies during his 1883 visit.
English language instructions came to Pen in the late 19th century in the form of primary English classes started by Christian missionaries. This school moved to Alibag with the shifting of the district headquarters there. The Pen Municipal council started five classes, and subsequently Vinayak Narayan Manohar started the remaining two classes, naming them Pen Candidate Classes.The Jewish community who lived in the Pen village adopted the last name of them as "PenKar" and it is still being continued where ever the decedents of their people even in USA,Canada and Israel they continue with the same last name. Plague caused this school to be closed. This English-Marathi school was later revived in the first decade of the 20th century. Balkrishna Shankar Karandikar started an industrial training school around this time; the Kokan Vidyalaya, which was later closed as a result of his arrest for involvement in Jackson's shooting at Nasik in 1909. On 10 April 1910 the Pen Education society was formed, Pen Private High School was started, in Shankar Khanderao Phanse's bungalow (now the Maternity Hospital), from where it shifted in October 1912, to its present premises at the foot of Peer Dongri.
