| Katharina Fritsch: Hahn/Cock, 2013 in Trafalgar Square|
Galleries aside, London grows ever more artistically interesting. I rather like Fritsch's 15 footer poking fun at Nelson's Column. But pausing only to note of that the German word hahn has the same double meaning as cock in English, here's my choice of less publicised sculptural works - some permanent, some temporary - you can see out and about in London this summer.
Dale Chihuly: The Sun, 2014 at Berkeley Square
The latest international venue for this Dale Chihuly spectacular is Berkeley Square, till the end of the year. It consists of 1,573 hand-blown glass elements from the glass master's studio in Seattle, where for 35 years now he has directed others rather than blowing the glass himself (Chihuly was blinded in one eye by glass in 1976 - not in the studio, but when thrown through a car windshield). The Sun works well both by day, when the effect is of an impossibly exotic tree, and when illuminated each night.
Cecil Balmond: H_Edge at Bishop's Square, Spitalfields
Anglo-Sri Lankan designer, architect and artist Cecil Balmond's urban walk-in hedge will hover over a reflecting pool opposite the Allen & Overy building until October. The 'leaves', I suppose, are thousands of curvy x-shaped aluminium plates, held tensely in place by stainless steel chains. Balmond (co-designer of several Serpentine Pavilions and, with Anish Kapoor, of the ArcelorMittal Orbit) sees it as embodying 'infinity and zero' - so it may be just me, but I found it an attractively kinky from of foliage. And, like 'The Sun', it is dramatically illuminated at night.
Gavin Turk: Nail, 2011 at One New Change, St Paul's
What god-sized object used to be pierced by this 12 metre bronze, treated to take on a stable look of rust on an equally blown up - and so unnatural - scale? Whatever it was, the nail seems stranded between the resonance it would have in the nearby St Paul's Cathedral and the role it didn't play in building the new shopping centre outside which it stands. Gavin Turk's comic riff on Claes Oldenberg certainly puts the nearby bollards in their place.
David Batchelor: Chromolocomotion, 2014 at St Pancras Station
Oliver Marsden: Dub, 2010 at 10 Rochester Row, Westminster
Oliver Marsden is best-known for meditative paintings which explore the intersection of intense colour with the mystical power of circular formations to produce what he calls 'a state of resonance' - as if sound waves were caught in a liquid speaker. I was surprised to hear that he'd applied the approach to the facade of a building, but the 'luxury living' of 55 apartments and penthouses at Ten Rochester Row hums with satisfying subtlety.
