King William St. is only part of the overall King William Historic District of Downtown San Antonio. These houses are old, wonderfully restored mansions on beautiful treed lots. Truly a treat to walk through and see. During Fiesta celebrations in April, King William has parades and a street faire with food, confetti, eggs, and lots of fun. This place is definitely for people who want the downtown life. Sightseers can visit here to or from the awesome San Antonio riverwalk. King William is also close to some nice art galleries, and there are often cultural events going on here or near here.
