In places the canal forms the edge of public parks, between Greenford, Yeading, Northolt and nearest the city at Meanwhile Gardens, North Kensington (a part also known here as Kensal Vale). The largest park adjoining is Horsenden Hill, Sudbury. It forms one long boundary of elongated Kensal Green Cemetery, a Grade I diversely wooded site of featuring two conservation areas and grave memorials such as to Brunel and two British Princes; this continues with St Mary's Roman Catholic Cemetery where the interred include Mary Seacole, two Cardinals, a Bonaparte and two Polish leading spies against Nazi Germany: Andrzej Kowerski (aka Andrew Kennedy) and Krystyna Skarbek (aka Christine Granville). The cemeteries front the canal with a wall since the era of urban grave robbing in the 19th century and a disused gate. The opposite (south) bank is the towpath side which provides canal views from many buildings and those visiting.
