It all started on 09/09/09. That memorable date, September 9 2009, marked the debut of theartsdesk.com.

It followed some hectic and intensive months when a disparate and eclectic team of arts and culture writers went ahead with an ambitious plan – to launch a dedicated internet site devoted to coverage of the UK arts scene.

Many of our readers today may have forgotten the arts journalism atmosphere of the first decade of the new century – especially the decimation of traditional broadsheet arts coverage that followed the financial crisis of 2008.

Botanical forms, lurid and bright, now tower above a footpath on a moor otherwise famed for darkness and frankly terrible weather. But the trio of 5m-high contemporary sculptures grow in place here, drawing life from limestone soil. These metallic buds, blooms and supersize tubers reflect a deep, tropical past that predates the very English landscape we now associate with this part of the world.

A traditional Korean house has appeared at Tate Modern. And with its neat brickwork, beautifully carved roof beams and lattice work screens, this charming dwelling looks decidedly out of place, and somewhat ghostly. Go closer and you realise that, improbably, the full-sized building is made of paper. It’s the work of South Korean artist Do Ho Suh (main picture).

The best way to experience Ed Atkins’ exhibition at Tate Britain is to start at the end by watching Nurses Come and Go, But None For Me, a film he has just completed. It lasts nearly two hours but is worth the investment since it reveals what the rest of the work tries hard to avoid openly confronting – grief.

Stonehenge is about 5,000 years old; three photographic artists currently exhibiting in the visitor centre are all under the age of 25. The juxtaposition of 21st century and the ancient world has been facilitated by Shout Out Loud, a youth engagement programme from English Heritage, custodians of this historic monument. In collaboration with Photoworks, this gives rise to the first ever exhibition of new photography at the site.

The railways that we built in India may be well known, but I bet you’ve never heard of the Customs Line, a hedge that stretched 2,500 miles across the subcontinent all the way from the River Indus to the border between Madras and Bengal – the distance between London and Istanbul. Comparable in scale to the great Wall of China, this 40-foot high barrier was created to prevent the smuggling of salt.

On walking into Mikalene Thomas’s exhibition at the Hayward Gallery my first reaction was “get me out of here”. To someone brought up on the paired down, less-is-more aesthetic of minimalism her giant, rhinestone-encrusted portraits are like a kick in the solar plexus – much too big and bright to stomach. Could I be expected to even consider accepting these gaudy monstrosities as art?

Sebastian Copeland’s images of the Arctic may look otherworldly – with their tilting cathedrals of ice, hypnotic light, and fractured seascapes that seem to stretch to infinity – but it would be a mistake to see them that way.
