Somerset has 11,500 listed buildings, 523 scheduled monuments, 192 conservation areas, 41 parks and gardens including those at Barrington Court, Holnicote Estate, Prior Park Landscape Garden and Tintinhull Garden, 36 English Heritage sites and 19 National Trust sites, including Clevedon Court, Fyne Court, Montacute House and Tyntesfield as well as Stembridge Tower Mill, the last remaining thatched windmill in England. Other historic houses in the county which have remained in private ownership or used for other purposes include Halswell House and Marston Bigot. A key contribution of Somerset architecture is its medieval church towers. Jenkins writes, "These structures, with their buttresses, bell-opening tracery and crowns, rank with Nottinghamshire alabaster as England's finest contribution to medieval art."

Tracks include Tucson Raceway Park and Rillito Downs. Tucson Raceway Park hosts NASCAR-sanctioned auto racing events and is one of only two asphalt short tracks in Arizona. Rillito Downs is an in-town destination on weekends in January and February each year. This historic track held the first organized quarter horse races in the world, and they are still racing there. The racetrack is threatened by development. The Moltacqua racetrack, was another historic horse racetrack located on what is now Sabino Canyon Road and Vactor Ranch Trail, but it no longer exists.

A party's consent to a treaty is invalid if it had been given by an agent or body without power to do so under that state's domestic law. States are reluctant to inquire into the internal affairs and processes of other states, and so a "manifest violation" is required such that it would be "objectively evident to any State dealing with the matter". A strong presumption exists internationally that a head of state has acted within his proper authority. It seems that no treaty has ever actually been invalidated on this provision.[citation needed]
