anchor.diff:      <p>Almost as influential as the visitors was the décor, which was to set the fashion for London reception rooms for nearly a century. The mainly Louis XIV interiors created a stunning backdrop for the Sutherlands’ impressive collection of paintings and objets d’art, many of which can still be seen in the house today.</p>
       <p>In 1913, Lord Leverhulme, a Lancastrian, bought the lease for the nation and Stafford House became Lancaster House. As one-time home to the London Museum, the house has been an important centre for government hospitality ever since.</p>

       <p>On entering the house through the portico, the hall opens up to reveal a sweeping staircase in a deliberate echo of Versailles. This and the rococo balustrade are both part of Benjamin Wyatt’s original design.</p>
  -     <p>The great skylight and the glowing colour of the walls are the work of Charles Barry who used scagliola (a coloured paste containing mineral fragments) to simulate marble on the walls and the granite-like pillars.</p>

       <p>The long gallery can hold up to 200 people seated theatre-style or 150 for a seated dinner. Alternatively, it can accommodate a conference table for up to 60, with a further 120 people seated beside and behind the table. The long gallery provides a dramatic backdrop for big events; it is perfect for opening or closing ceremonies and receptions for up to 350 people.</p>
       <p>More than 35 metres in length, the long gallery dominates the whole of the east side of the house. With 18 windows and a large ornate skylight, the room is filled with natural light.</p>
       <p>Winston Churchill gave a coronation banquet for the newly crowned Queen Elisabeth II here in June 1953. More recently, the long gallery has been used for a number of top-level international summits, wedding receptions, fashion shows and filming.</p>
       <p>The ceiling, painted by the Italian artist Guercino, shows Saint Chrysogonus borne to heaven by angels. The chimney piece below features ormolu decorations from France and a shelf supported by gilded allegorical figures of Architecture and Painting.</p>
       <p>An anteroom at the end of the gallery contains Zelotti’s Cupid receiving an apple from the Graces. The tall, heavy doors are decorated with the Sutherland monogram.</p>

  -   <p>The music room can accommodate a boardroom table for 36 and theatre style for 100. It can also accommodate lunch or dinner for up to 76 people.</p>
  -   <p>With windows opening onto a balcony overlooking Stable Yard and recesses flanked by Corinthian columns, the music room provides a grand setting for meetings, press briefings or formal dinners.</p>
  -   <p>The splendour of the rooms reflects the house’s long association with music. Throughout the 19th century, few leading musicians came to London without appearing at one of the Sutherlands’ evening parties. Frederic Chopin played here for Queen Victoria and Prince Albert in 1848. The house records also show that he gave lessons to the young Lady Constance.</p>

  -   <p>Between the windows, which look onto St. James’s Park, candelabra are supported by a swarm of cherubs. The ornate chimney pieces are flanked by old bell pulls with faceted crystal centres, recalling the days when the house employed a large retinue of servants.</p>
