Adjacent to the city's Cardiff Bay area, Grangetown is experiencing a period of gentrification and improvements in its infrastructure.

Grangetown is a diverse and multiracial district and has a significant population of Somali, Asian and mixed-race residents.

Gwyddoniadur Cymru, the Welsh-language version of the Encyclopaedia of Wales, uses Grangetown, but notes the existence of Trelluest.

The monks established a monastic grange there which they held until they were expelled in around 1290 by Gilbert de Clare, Lord of Glamorgan.

The last farmer was a landowner called Lewis ap Richard who is also known as a patron of the Welsh-language poet Rhys Brychan.

[16] In 1857 Baroness Windsor (whose Plymouth Estate owned the land) obtained an Act of Parliament to build housing in the area, intending to call it The Grange.

[18] Grangetown's original public library on Redlaver Street was built 1900–1901 in the Tudor Gothic style.

On 2 January 1941, during the full moon, around 100 German World War 2 planes raided Cardiff for over 10 hours.

A cellar at Hollyman Brothers Bakery on the corner of Corporation Road and Stockland Street was being used as a bunker.

On the side of the building you can see a plaque in memory of the victims, which was erected by the Grangetown Local History Society.

Grangetown is part of the Cardiff South and Penarth constituency which returns one MP to the UK Parliament and one MS to the Senedd.

Grangetown has at least ten Christian places of worship including Grangetown Baptist Church and the Salvation Army citadel as well as a Hindu temple on Merches Place, mosque called Masjid Abu Bakr on Clydach Street and newly built Masjid called Markaz At-Tawheed on Penarth road.

The church of St Paul, Paget Street, was built between 1889 and 1902, largely at the expense of Lord Windsor.

It uses an "eccentric" palette of materials including pennant rubble, pink sandstone and Portland cement.

[31] The 'Roxe Jam' hip-hop and graffiti festival takes place annually in Sevenoaks Park, Grangetown, on the last weekend of July.

The event was set up in memory of a young graffiti writer, Bill Lockwood aka Roxe, who was killed in a road accident.

The main highlight of the event is the legal painting of a 140 m long wall which runs parallel to the Cardiff to Penarth railway line.

The parish church of St Paul, Paget Street, was used as the location for the BBC's Doctor Who series episode Father's Day.

[41] North Grangetown Renewal Area (2005-2013) saw 500 homes refurbished in a rolling block programme with new roofs, windows and rendering.

Improvements included planting of trees and the creation of a new public open space, Gerddi Courtmead Gardens, parallel to Hereford Street.
