Abstede is a neighbourhood of the Dutch city of Utrecht. According to the 19th-century historian A.J. van der Aa, Abstede (formerly also called Abtstede or Abstade) derives its name from an abbey of Cistercian nuns. The abbey was closed in 1227, when the nuns were moved against their will by Wilbrand van Oldenburg, bishop of Utrecht, to the St. Servaas Monastery, in the city, that he himself founded. Until the end of the eighteenth century, Abstede was a separate jurisdiction, like a village. Between 1818 and 1823, Abstede was a separate municipality again. It was annexed by the city of Utrecht in 1823.

The Centraal Museum is the main museum in Utrecht, Netherlands, founded in 1838. The museum has a wide-ranging collection, mainly of works produced locally. The collection of the paintings by the Northern Mannerist Joachim Wtewael is by a long way the largest anywhere in the world. Other highlights are many significant paintings by the Utrecht Caravaggisti, such as Gerard van Honthorst and Hendrick ter Brugghen. Both of them travelled to Rome in the early 17th century to study the works of the Italian master Caravaggio. In the previous generation, as well as Wtewael, Abraham Bloemaert and the portraitist Paulus Moreelse were the most significant Utrecht painters, with Jan van Scorel still earlier.

It is the youngest university in the Netherlands and houses about 530 students. It is also the only university offering a degree programme in humanistic studies.

The Kromme Rijn (Dutch pronunciation: [ˈkrɔmə ˈrɛin]) ("Crooked Rhine", for its many bends) is a river in the central Netherlands. In Roman times, this northernmost branch of the Rhine delta was the main distributary of this major European river. Along its banks the Romans built their frontier castella part of the Limes Germanicus. Since the Middle Ages, however, the stream lost its importance as it silted up, and eventually it is nearly cut off from the Nederrijn-Lek main artery. Yet it retained the name "Rhine". The Kromme Rijn splits off the Nederrijn-Lek main artery at the old town of Wijk bij Duurstede (called Dorestad in the early medieval period), after which it twists and turns through the province of Utrecht, past the towns of Cothen, Werkhoven, Odijk and Bunnik, and ends in the moat of the city of Utrecht. Originally, the city of Utrecht was built by the Romans at a ford near the place where the Kromme Rijn forks into rivers Vecht (north) and Leidse Rijn (west); the last stretch within the city walls, however, was channelised to form the Oudegracht canal. Rivers Leidse Rijn and Vecht extend from the city moat and are the continuation of the Kromme Rijn.

St. Peter's Church (Dutch: Pieterskerk) is a Reformed and former Roman Catholic church in the city of Utrecht in the Netherlands, dedicated to Peter the Apostle. It is one of the city's oldest churches. Its construction began in 1039 and it was inaugurated on 1 May 1048 by Bernold, Bishop of Utrecht (although the lost west towers were probably only finished about a century after the inauguration). The church was the eastern end of Utrecht's "Kerkenkruis", of which the Domkerk the centre is. Characteristic of the Romanesque style in which it is built are the church's large nave pillars, each hewn from one piece of red sandstone, and the crypt under the choir. The building is now used by the Walloon Church.

St. Paul's Abbey was a monastery in Utrecht in the Netherlands. In 1580 it was the second oldest monastery in the Netherlands, second only to Egmond Abbey in the north.

Museum Maluku, also known by the abbreviation MuMa, was a museum dedicated to the Maluku Islands and the Moluccan community living in the Netherlands. Museum Maluku was located in the city of Utrecht. Due to inadequate financial means Museum Maluku had to close its doors. Part of its collections found a home at other museums and institutes.

The Letters of Utrecht (Dutch: De Letters van Utrecht) form an endless poem in the stones of a street in the center of the Dutch city of Utrecht. Every Saturday at 13:00, the next letter is hewn into the next cobblestone, with the intent to continue for as long as there are Saturdays. It takes about three years to publish an average sentence. Every year the poem grows by about five meters. Every few years another poet extends the poem.The poem is created by members of Utrechts Guild of Poets and was started by Ruben van Gogh, Ingmar Heytze, Chrétien Breukers, Alexis de Roode, and Ellen Deckwitz. The poem was continued in February 2013 by Mark Boog, in December 2015 by the Iraqi-Dutch Baban Kirkuki, in December 2018 by Vicky Francken and in March 2022 Anne BroeksmaThe first 648 letters (one for every Saturday since 1 January 2000) were unveiled on 2 June 2012 by Utrecht's mayor, Aleid Wolfsen, who contributed the letter hewn on location that day. Since this opening, stone masons from the Lettertijd guild have hewn the characters into subsequent stones every Saturday. The font was designed for the purpose by Hanneke Verheijke of Avant la Lettre. Stones with year numbers mark the planned route and turn the growing line of letters into a meter of time. If the citizens continue to fund the making of stones long enough, the line of poem will itself draw the letters U and T on the map of the city, and future citizens can decide on the future route beyond the year 2350. A future there will be, but it is unknown; the poet keeps the continuation of the poem beyond the most recently published letter secret. The project is expressly intended for the benefit of future people. It is funded by contributors who donate Letters and add stories to them, which results in a growing number of people with an interest in the project's continuation and generates excess funds for practical good causes. The effort is driven by a not-for-profit foundation, Stichting Letters van Utrecht and run by volunteers. The concept for the Letters of Utrecht grew out of Milliongenerations' work of milliongenerations.org and was inspired by the efforts of Danny Hillis and the Long Now Foundation to build a 10,000 Year Clock to promote long-term thinking. The Long Now Foundation had contributed a stone cut from the Sierra Diablo Mountain Range in Texas where the 10,000 Year Clock is being built. That stone now carries letter number 1 (a "J").As a social sculpture, The Letters of Utrecht refer to the 7000 Oaks of Joseph Beuys in Kassel, Germany. Beuys named his work City Forestation Instead of City Administration and conceptualized man's dependency on nature, referring to it as a 'Wärmezeitmaschine' ('heat-time-machine'). The Letters of Utrecht evoke civilizations' growth of knowledge and the dependency of future inhabitants on the actions of contemporaries and visualize the passing of time and the reality of the future.The continuation of the Letters depends on the willingness of citizens to sponsor the creation of a letter in return for having a name or dedication engraved in the side of the cobblestone and on a website, which hopes to let people consider their reputation among posterity rather than their status among contemporaries.

Traiectum was a Roman fort, on the frontier of the Roman Empire in Germania Inferior. The remains of the fort are in the center of Utrecht, Netherlands, which takes its name from the fort.
