Established in 768 A.D. as the shrine of the Fujiwara family, Kasuga has been rebuilt several times.
Note that some of the pictures above, especially early in the page, are of Nigatsudo and Hokkedo, which are actually part of Todai-ji. Due to Golden Week crowds, I was unable to get into several of the most popular sites in Nara and Kyoto, including Kasuga Taisha's inner area. I'd like to return and revisit Todaiji and Kasuga Taisha some day.
Opening by 6:30 AM, Kasuga-Taisha usually closes around 5:30 or 6 PM. Admission to the inner area is 500 yen. There's a botanical garden (9:00-17:00, closed Mondays in winter, 500 yen) and a treasure house (9:00-17:00, 400 yen).
