Along with Charlotte Square, St Andrews Square shows off the splendour of Edinburgh's New Town. Old and new buildings come together here with the Palladin country house (now housing the headquarters of the Royal Bank of Scotland) and the famous Harvey Nichols store on the southern side of the square.
St Andrews Square lies at the eastern end of George Street and is just a 5 min walk from Edinburgh's main bus station.

Harvey Nicks is on the East side, RBS HQ (as was) is now opposite the airport. St Andrew Square looks especially great in autumn and winter. Go into the RBS building on the east side (it's a branch) and look straight up - to a fantastic paned dome which you'll recognise as the patterned background on your Royal Bank tenners! This square was opened to the public in April 2008 for the first time in 238 years after a massive £2.6m development. There's a coffee place, seating and it looks great. I'm told that at night it looks fabulous from the top floor restaurant at Harvey Nicols that is on the square.
