Hush Hush is a project by artist Steve Messam. Situated in an old lead mining works (known as a hush) stretching 450m in length, this two-week long installation in July and August 2019 featured hundreds of saffron-yellow flags in one of the largest artworks yet created in the UK.The Teesdale valley is part of the North Pennines Area of Outstanding Natural Beauty (NP AONB) and the artwork was created in partnership with the local authority. Plant and animal conservation is a vital aspect of this AONB and the area is a designated UNESCO Global Geopark. All of the Hush materials were recycled and its impact assessed against the needs of protected fauna and flora in the Teesdale valley.
