The Stockholm tramway network forms part of the public transport system in Stockholm, the capital city of Sweden. Beginning with horse trams in 1877, the Stockholm tram network reached its largest extent in 1946. Many of the former suburban tram lines became parts of the Stockholm Metro between the years 1950-1964. In September 1967, in conjunction with the Swedish switch from left-hand to right-hand traffic, the last parts of the once large inner city street running tram network were closed. What little remained of the former network following 1967 were isolated suburban feeder lines to the Metro. However, in 1991 a 3 km (1.9 mi) long heritage line opened to the recreational area Djurgården; and in 2000, the non-radial half-circle line Tvärbanan opened with articulated low floor vehicles connecting an inner ring of Metro and commuter rail stations just outside the inner city proper, with subsequent extensions in 2003 and 2014; and in 2010 the heritage line was extended and converted to a regular service line.

Stockholm Municipality or the City of Stockholm (Swedish: Stockholms kommun or Stockholms stad) is a municipality in Stockholm County in east central Sweden. It has the largest population of the 290 municipalities of the country, but one of the smallest areas, making it the most densely populated. It is also the most populous municipality in the Nordic countries. Although legally a municipality with the official proper name Stockholms kommun, the municipal assembly (kommunfullmäktige) has decided to use the name Stockholms stad (City of Stockholm in English) whenever possible. This is purely nominal and has no effect on the legal status of the municipality. Geographically, the city comprises the Stockholm City Centre and two suburban areas, Söderort (South Stockholm) and Västerort (West Stockholm). Administratively, it is subdivided into 14 districts (sometimes incorrectly called "boroughs" in English), which are administered by district councils (stadsdelsnämnder).

Tysta skolan ('The Silent School') was a private school for deaf-mute children founded in 1860 by educator Johanna (Jeanette) Berglind in Stockholm, Sweden. The name refers to the initial teaching method, which was described as the "write-sign method". From 1866 to 1910, the school was located on a property at Norrtullsgatan 51–67 in present-day Vasastan. It was then moved to Lidingö where it initially provided practical and theoretical continuing education for deaf-mute girls before being converted into a vocational school in the 1930s. The school moved back to Stockholm in 1947 where it continued to teach until its closure in 1971. The Tysta Skolan Foundation continues to exist and distributes the income from the funds in the form of scholarships and grants.

Lärkstaden (Swedish for "Lark City") is an urban area within the city district of Östermalm in central Stockholm, Sweden. The name originates from the large block "Lärkan" which used to dominated the area before the present buildings were built in 1907. Many of the blocks added at this time were given names such as "piplärkan" pipit, "tofslärka" (Crested lark), "trädlärka" Woodlark, and other bird names.Though the area has no official extent, it is said to be delimited by the streets Odengatan, Karlavägen, Valhallavägen, and Uggelviksgatan, if nothing else because of the contrast between the small-scale character of the neighbourhood and the blocks surrounding it.

Stockholm East Station (Swedish: Stockholms östra station) or Stockholm Ö is a railway station on the Roslag Railway in Stockholm, Sweden. The present station was inaugurated in 1932 and located on Valhallavägen in northeastern central Stockholm, close to the Royal Institute of Technology (Tekniska Högskolan), replacing an older provisional station from 1884 which was located some hundred metres to the north. Originally, the building had the offices of SRJ, the company owning and managing the Roslag Railway. There are still offices in the building for the company which is operating the traffic at present. The building also includes a restaurant, which has the same interior as when the building was new, something which is appreciated by the customers. The restaurant is well known as a place where supporters of sports club Djurgårdens IF like to go, as it is relatively close to the Stockholm Olympic Stadium, the classic former home field of Djurgårdens IF football team.It is located in conjunction with the Stockholm metro station Tekniska högskolan. It is now the southern end station of the Roslag Railway. Earlier, some trains continued on a tram line to Engelbrektsplan next to Humlegården. The station makes up the background in the 2011 Swedish movie Stockholm Östra, starring Mikael Persbrandt and Iben Hjejle.

Tekniska högskolan is a station on the red line of the Stockholm metro, located in the districts Östermalm and Norra Djurgården, near the Royal Institute of Technology (Kungliga Tekniska högskolan). The station was opened on 30 September 1973 as the northern terminus of the extension from Östermalmstorg. On 12 January 1975, the line was extended further north to Universitetet. Tekniska högskolan metro station is connected to Stockholm East Station or Stockholms östra, a station on the Roslagsbanan railway, and a terminal for buses towards Norrtälje and Vaxholm. The art in the station was done by Lennart Mörk and features a common theme of technology, the four elements, and the laws of nature. Quotes from the history of science are interspersed with paintworks and sculptures such as Newton's apple, the wings of Icarus, and the five Platonic solids representing the classical elements – a dodecahedron, symbolising the aether and containing the "black hole of the universe", is suspended from the central ceiling. As one of the first "cave stations" where the walls follow the contours of the underlying bedrock, Tekniska högskolan (along with nearby Stadion) metro station was awarded the 1973 Kasper Salin Prize.
