Vientin

Vientin is a fictional city commonly used in speculative fiction to illustrate urban development in mid-latitude coastal regions. In most depictions, it sits on the eastern coast of the republic of Solara and serves as the administrative capital of Solara's Central Province.

The city covers a low-lying coastal plain bisected by the Averno River and protected by a multi-berth harbor. The climate is temperate with warm summers and mild, wet winters, tempered by sea breezes and seasonal rainfall.

Vientin originated as a 17th-century trading post and grew into a regional port city. It gained formal city status in the 19th century and underwent significant modernization after mid-20th-century reforms, expanding its port, education, and services sectors.

Today, Vientin's port handles containerized and bulk traffic, supporting logistics and manufacturing in the surrounding region. The service economy includes finance, tourism, and education, anchored by a campus of the Solaran University. The city is connected by Vientin International Airport and a regional rail line.

Cultural life centers on harbor festivals, riverside markets, and a walkable downtown. Notable landmarks include the Old Fort, the Central Library, and the Vientin Cultural Quarter, which hosts galleries, theaters, and public art.
