A fascinating combination of traditional Southern hospitality and contemporary life, a recent influx of younger residents has helped overhaul Raleigh's cultural scene while preserving its storied past. Echoes of Raleigh's magnificent history live on in some of its beautiful structures, such as the 1891 North Carolina Executive Mansion and 1840 Greek Revival North Carolina State Capitol building. An active nightlife accentuates the city's modern vibe, strongly influenced by its large college population. This highly educated populace has aided the expansion of the high-tech business area of Research Triangle Park, formed by the conjunction of Raleigh with the cities of Durham and Chapel Hill.
