A village of 451 people on a cliff above the Atlantic, 30 km from Lisbon, with a rock pool at the bottom that fills when the tide goes out. Free, small, and busier at the railing than anywhere else on this coast.

The point where mainland Europe stops: 140 metres of cliff, a stone cross with a line of Camões on it, and a lighthouse working since 1772. Free, always open, and windier than you are dressed for.

A convent of eight friars built into granite boulders in 1560, with cork on the ceilings and doors you have to stoop through. The hardest Sintra monument to reach and the one people remember longest.

Thirty three hectares of botanical garden with a palace in the middle of it, at €12 for both. The quietest of the Sintra monuments, and the one where the garden matters more than the building.

A 10th-century wall that runs along the ridge above the town, with two towers and the best view in Sintra. Cheaper than Pena, emptier than Regaleira, and the one that closes when the wind gets up.

The yellow and red palace on the top of the Sintra hills, built by a German prince in the 1840s on the ruins of a monastery. What it costs, when it opens, and how to see it without the queue.

A palace, a chapel and a garden full of tunnels, built between 1904 and 1910 by a millionaire with a taste for symbols. The spiral well everyone photographs is here. What it costs, when it opens, and how to do it in two hours.

The two white cones you see from every street in Sintra are chimneys, and the kitchens under them are the best room in the building. The oldest royal palace left in Portugal, in the middle of town, at €13.

Ten streets between the National Palace and the hill, with the best free walk in Sintra running down into them. The part of town most people cross in fifteen minutes on their way to somewhere else.
