Only seven houses remain from the early 20th century in the city of Bogota, Colombia. The houses were built in the 1920s and 30s, and are now in disrepair.
The city is now home to more than 100,000 people, many of whom live in the surrounding area. It is also the site of the largest concentration of people living in the U.S. since World War II. It has been the scene of a series of protests against the city's development, particularly in recent years.
