Bluegrass region

It makes up the central and northern part of the state, roughly bounded by the cities of Frankfort, Paris, Richmond and Stanford.

[3][4] The Bluegrass region is characterized by underlying fossiliferous limestone, dolomite, and shale of the Ordovician geological age.

On the south and west, it borders the Pennyroyal Plateau, (also called the Pennyrile), with Muldraugh Hill, another escarpment, forming the boundary.

The first commercial winery in the United States was opened in the Bluegrass region in 1801, in present-day Jessamine County by a group of Swiss immigrants.

Since the late 20th century, the area has become increasingly developed with residential and commercial properties, particularly around Lexington, the business center.

In 2006, the World Monuments Fund included the Bluegrass region on its global list of 100 most endangered sites.

Kentucky's Inner Bluegrass region features hundreds of horse farms.
