Jal Mahal

Approach along Amer Road and the city simply stops. The traffic, hoardings and dust of Jaipur's northern edge give way to a sheet of open water, and set in the middle of it — apparently afloat, with no causeway and no obvious way in — sits a low red-sandstone palace with a chhatri at each corner.

• Jal Mahal is one of the few monuments in India you meet entirely at a distance, and that distance turns out to be the point. The lake came first.
• Raja Man Singh of Amer dammed the Dravyavati river in about 1610, creating Man Sagar as a reservoir for a region that has never had water to spare.
• The palace in its middle followed roughly a century later, around 1699, and was enlarged in the early eighteenth century under Maharaja Jai Singh II — the same ruler whose grid-planned city, laid out in 1727, lies a few kilometres south.
• It was raised as a retreat for the Amer court rather than a residence: somewhere to be rowed out to on a summer evening, not somewhere to live.
• Understand the arithmetic and the building changes shape in your mind.
• Jal Mahal has five storeys, but when Man Sagar is full, four of them are underwater.
• What you see — the arcaded terrace, the four octagonal chhatris, the Chameli Bagh roof garden — is the top floor alone, the visible tenth of an iceberg made of sandstone.
• The lake is shallow — about 4.5 metres at its deepest — which is part of why the palace has survived three centuries of immersion, helped by a patient restoration in traditional lime-and-surkhi mortar.
• And here is what no tout at the railing will tell you plainly: the interior is not open to visitors.
• No entry, no boat you can buy a seat on, no ticket counter.
• Anyone offering you one is selling nothing.
• For the vegetarian traveller, Jal Mahal is a viewpoint, not a meal stop.
• The shore has hawkers, chai and photographers in a hurry; no restaurant worth planning around, and nothing on the promenade comes with a dependable assurance about egg.
• Treat it as the twenty-minute pause between Amer and the old city, and eat at either end — roughly five kilometres south, Bani Park and Station Road hold the reliable pure-vegetarian houses.
• A useful rule across Jaipur: 'pure veg' here dependably means no meat, but it is not a statement about egg.
• If eggless matters to you, ask the counter directly rather than trusting the board.
• Come at the edges of the day.
• First light brings mist off the water and, from November to February, migratory birds — Man Sagar has been logged with well over a hundred species, a real recovery for a lake once written off as dead.
• Late afternoon drops the sun behind the palace and turns the sandstone the colour of wet brick.
• Midday is flat, hot and thick with coaches.
• Park, walk the promenade, decline the camel photographers politely, give it half an hour.
