I realise I've missed out for this year but can anybody tell me about buildings/sights that are only open to the public in late September.
Somebody told me they include the likes of the Lloyds Insurance building and the "Gherkin" but that it only applies on one Sunday.
Please can anyone tell me:
1. What date is it?
2. Is there a web site that lists them?
3. What are the opening hours?
4. Do there tend to be long queues?
5. Bearing in mind increased security levels does the scheme actually still run?
