The fourth-largest city and a municipality of the Netherlands,
capital and most populous city of the province of Utrecht.
It is located in the eastern corner of the Randstad conurbation,
in the very centre of mainland Netherlands; it had a population of
359,355 as of 2021. Utrecht's ancient city centre features many
buildings and structures, several dating as far back as the High Middle
Ages. The cityscape is dominated by the Dom Tower, the tallest belfry in
the Netherlands and originally part of the Cathedral of Saint Martin.
Another landmark is the old centre and the canal structure in the inner
city. The Oudegracht is a curved canal, partly following the ancient
main branch of the Rhine. It is lined with the unique wharf-basement
structures that create a two-level street along the canals. The inner
city has largely retained its medieval structure, and the moat ringing
the old town is largely intact.
