Сиденхэм тарихы: Кристалл сарайдан қазіргі күнге дейін

In 1851 the Great Exhibition in Hyde Park was housed in an immense glass building, called the Crystal Palace. In 1854 the building was bought by a private company, dismantled and re erected at Penge Peak on Sydenham Hill (now Crystal Palace Park). Exhibitions, concerts, conferences and sporting events were held at the Crystal Palace (until it burned down in 1936), and Sydenham became a fashionable area with many new houses being built. In 1871 the French impressionist painter Camille Pissarro produced The Avenue, Sydenham, a largely still recognisable view on today's Lawrie Park Avenue; the painting is now owned by the National Gallery. In 1860 the Walter Cobb department store at Lawrie Place, Kirkdale (now known as Cobbs Corner) opened, lasting until the 1980s. In 1872, the Children's Hospital, Sydenham opened. It closed in 1991, its services being now part of the University Hospital Lewisham. In 1884, Upper Sydenham railway station opened on the Crystal Palace and South London Junction Railway linking Crystal Palace to London Victoria via Peckham Rye. The station and the line were poorly used despite new houses being built in the area, as passengers preferred to use other stations near by, Sydenham Hill (opening in 1863), Crystal Palace (Lower Level) and Sydenham which were on more direct routes. The ill fate of the Crystal Palace in 1936 saw patronage reduced and the route finally closed in 1954. Sydenham was attacked by enemies during the Second World War. The gas works were a target, but were never damaged. The railway which ran through Upper Sydenham station was damaged, and some homes in the area were destroyed.

Sydenham's main commercial area begins on Kirkdale around Cobbs Corner, continuing onto Sydenham Road, often known as "Sydenham High Street". It houses many independent shops, including a bakery, bookshop and several restaurants. Furthermore, Sydenham is noted for the number of independent coffee shops. Chain stores include Boots, Nando's, Lidl, Sainsbury's Local, Subway, Superdrug, Starbucks and Tesco Express. There is a Post Office branch and many estate agents. After recent closures, Natwest remains the only bank with a branch in the High Street. The first ever location of the Morley's chicken chain opened in Sydenham in 1985, and remains in operation today. Since the Transport for London and Lewisham Council funded high street upgrade in 2012–13, there is now a monthly market located within the pocket squares, known as "Queensthorpe Square" and "Venner Square". The 18th century Greyhound pub, demolished by a developer without council permission in 2013, was rebuilt and reopened in 2017.

Sydenham has a very active community, with several groups concerning the local area. Sydenham Town is the local website for the area, where residents can also voice their opinions in an on line form. The Sydenham Society is a Civil society formed in 1972 to represent the local community. It holds local events, works with organisations and authorities as well as campaigning for improvements to the area. Green Flag and Mayor of London Award winner, Sydenham Garden, was formed in 2002. It is a charity which is involved in improving the health of residents in the boroughs of Bromley and Lewisham. Sydenham with Forest Hill won a bid for the national Portas Pilot competition which provided a grant to improve high streets; extra money was provided from Lewisham Council and private developers. Annually every summer since 2009, the Sydenham Arts Festival is held, where there are workshops, music, family activities etc.
