Lancaster House in the context of "Foreign, Commonwealth and Development Office"

The London and Zürich Agreements (Greek: Συμφωνίες Ζυρίχης–Λονδίνου; Turkish: Zürih ve Londra Antlaşmaları) for the constitution of Cyprus started with an agreement on 19 February 1959 in Lancaster House, London, between Turkey, Greece, the United Kingdom and Cypriot community leaders (Archbishop Makarios III for Greek Cypriots and Dr. Fazıl Küçük for Turkish Cypriots). On that basis, a constitution was drafted and agreed together with two prior Treaties of Alliance and Guarantee in Zürich on 11 February 1959.

Cyprus was accordingly proclaimed an independent state on 16 August 1960.

The Lancaster House Agreement is an agreement signed on 21 December 1979 in Lancaster House, following the conclusion of a constitutional conference where different parties discussed the future of Zimbabwe Rhodesia, formerly known as Rhodesia. The agreement effectively concluded the Rhodesian Bush War. It also marked the nullification of Rhodesia's Unilateral Declaration of Independence, as British colonial authority was to be restored for a transitional period to internationally recognised independence, during which free elections under supervision by the British government would take place. Crucially, ZANU and ZAPU, the political wings of ZANLA and ZIPRA (who had been waging an escalating insurgency since 1964), would be permitted to stand candidates in the forthcoming elections. This was however conditional to compliance with the ceasefire and the verified absence of voter intimidation.

The Green Park, one of the Royal Parks of London, is in the City of Westminster, Central London. Green Park is to the north of the gardens and semi-circular forecourt of Buckingham Palace, across Constitution Hill road. The park is in the middle of a near-continuous chain of green spaces in Westminster that includes St James's Park, Hyde Park, and Kensington Gardens. To the northwest of Green Park is the district of St James's including, Lancaster House, Clarence House, and St James's Palace.

First enclosed in the 17th century by King Charles II, it was landscaped in 1820 and is notable among central London parks for having no lakes or buildings, and only minimal flower planting in the form of naturalised narcissus.
