Amersfoort (*1259 AD) is known for its well preserved late medieval city centre with canals, market squares, bridges and towngates, churches, chapels and monasteries. The Onze Lieve Vrouwetoren (*1444 AD) is one of the highest towers in the Netherlands and the characteristic medieval towngate known as De Koppelpoort is a symbol for the city. The Amersfoort Jazz Festival cherishes the beautiful inner city as a unique backdrop for its festival. Under the heading Amersfoort Jazz Heritage, the festival includes several unique and historical locations as full fledged venues, within walking distance of each other: de Observant, de Sint Aegtenkapel, de Mannenzaal and de Sint Joriskerk. All the above locations are included in the Amersfoort Jazz Heritage Walks on Saturday, May 16, which are guided citywalks leading up to a top notch World Jazz concert in de Observant. For international attenders, there is an English spoken guided walk available. All concerts are also publicly accessible, also without participation in the walk.
