Lambeth is a district in South London, England, in the London Borough of Lambeth. Lambeth was an ancient parish in the county of Surrey. It is situated 1 mile (1.6 km) south of Charing Cross, across the river from Westminster Palace. The population of the London Borough of Lambeth was 303,086 in 2011. The area experienced some slight growth in the medieval period as part of the manor of Lambeth Palace. By the Victorian era the area had seen significant development as London expanded, with dense industrial, commercial and residential buildings located adjacent to one another. The changes brought by World War II altered much of the fabric of Lambeth. Subsequent development in the late 20th and early 21st centuries has seen an increase in the number of high-rise buildings. The area is home to the International Maritime Organization. Lambeth is home to one of the largest Portuguese-speaking communities in the UK, and Portuguese is the second most commonly spoken language in Lambeth after English.
