Raleigh is the capital of the state of North Carolina as well as the seat of Wake County in the United States. Raleigh is known as the "City of Oaks" for its many oak trees, which line the streets in the heart of the city. Raleigh is an early example in the United States of a planned city, chosen as the site of the state capital in 1788 and incorporated in 1792 as such. Raleigh is home to numerous cultural, educational, and historic sites. The city is a major retail shipping point for eastern North Carolina and a wholesale distributing point for the grocery industry.
