Reference excerpt

Qiddiya City is an under-construction planned city and tourism megaproject situated along the Tuwaiq Escarpment in Riyadh Province, Saudi Arabia.

History The Qiddiya project was announced in April 2017 as part of Saudi Vision 2030, a national strategy aimed at diversifying the Saudi economy and increasing domestic tourism and entertainment spending. The project is supported by the Public Investment Fund and was envisioned as a large-scale entertainment, sports, and cultural destination near Riyadh. Construction began in early 2019. Early projections estimated annual visitation of up to 17 million by 2030 and the creation of approximately 325,000 jobs. The first phase of development was initially scheduled for completion in 2023 but was later revised, with timelines extending into the mid-2020s. The project includes major developments such as Six Flags Qiddiya City, the Aquarabia waterpark, a purpose-built Formula One circuit, and a planned Dragon Ball theme park, the first of its kind worldwide. These announcements prompted criticism from international observers and human rights organisations, who accused Saudi Arabia of attempting to sportswash its international image and raised concerns over the country's human rights record, including issues affecting LGBT people. Concerns have also been raised regarding labour conditions and human rights associated with the Qiddiya megaproject. In 2024, UK Export Finance classified the project as Category A under its social and environmental risk framework, citing the potential for significant adverse environmental and social impacts during construction and operation. Human Rights Watch reported risks linked to the Kafala system, wage theft, and heat stress affecting migrant workers involved in Saudi Arabia's megaprojects, including Qiddiya City. The Business & Human Rights Resource Centre (BHRRC) has additionally documented concerns over worker safety, including incidents involving vehicle strikes, falls from heights, and exposure to extreme heat at Qiddiya construction sites. Six Flags Qiddiya City opened on 31 December 2025 as the first operational asset of Qiddiya City, marking the initial public opening of the wider development.

Qiddiya company Qiddiya Investment Company (Arabic: شركة القدية للاستثمار) is a private Saudi company responsible for developing Qiddiya City in Riyadh Province. Owned by the Public Investment Fund, the company manages the city's projects and properties.

Worked examples

Example 1 — a first encounter with Qiddiya City

Start with the simplest possible case. Write down what Qiddiya City claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Qiddiya City before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Qiddiya City ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Qiddiya City

In research: Qiddiya City appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Qiddiya City in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Qiddiya City is common in secondary-school and first-year university syllabi. It links to neighbouring topics Megaprojects, Planned amusement parks, Planned communities in Saudi Arabia, so understanding it makes those chapters shorter.
In everyday life: Look for Qiddiya City outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
