Excellent gallery. It has big rooms which often feature large pieces and admission is free.

You would have seen the Brutalist towers and curves from afar. Upon entering the estate where the cultural centre is, you quickly realise the scale, the beauty and charm of this labyrinthine project. Barbican Centre's programming is top of the league across art, theatre, dance and music, both contemporary and classical, art forms. This place is an architectural and cultural institution boldly redefining the UK's cultural landscape.

The AA is Britain's oldest school of architecture, but anyone can take advangte of the great work going on there. You can catch really interesting public lectures and free exhibitions throughout the year. There are also occasional installations and event launches, a bijoux cafe and brilliant bookshop. A great place to hang out with the builders of the future.

The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.

The Garden is nestled behind walls and positioned close to the River Thames in Chelsea. The Thames location is no accident as back in 1673 the Worshipful Society of Apothecaries chose their Chelsea village site for its proximity to the river to make the most of its warm air currents. It also gave them a base to moor their barge, allowing them to conduct plant finding expeditions in surrounding areas and to teach their apprentices to identify plants.
