This year's architectural home tours are led by the seasoned volunteers at Pasadena Heritage. Pasadena Heritage is one of the oldest historic preservation groups in Southern California and the second largest in the state. With more than 2,000 members, it is also one of the City of Pasadena's largest membership organizations. Pasadena Heritage offers several public educational programs each year. Its Old Pasadena Walking Tours, custom bus tours, and Annual Spring Home Tour attract hundreds of visitors annually. The Craftsman Weekend, a three-day event held in October, focuses on the American Arts and Crafts Movement and its expression in Pasadena. Activities include lectures, restoration workshops, a house tour, and exhibits of antique and fine reproduction furnishings of this popular period in the arts and architecture. More than 4,000 people participated in the recent Craftsman Weekend.
