The city of La Paz has a consistently decreasing volume of colonial buildings, mostly centered around the vicinity of the Plaza Murillo. Due to a lack of funds and the inability of property owners to pay for restorations to colonial buildings, many have been torn down, or are in a dilapidated state. As historic buildings are more expensive to keep, land owners find it less of a burden to construct more modern buildings as opposed to keeping the old ones. Although there has been an increasing number of projects and propositions to restore some of the city's colonial buildings, the future of these historic edifices remains uncertain.
