Maravilhas confirmadas

• As estradas valirianas

Como você mencionou na pergunta, ele montou um desses com Illyrio Mopatis.

• A parede

Ele irritou-se, como mencionado na pergunta.

• O Titã dos Bravos

Ele não esteve em Bravos em A Storm of Swords . Nunca é mencionado mais tarde que ele foi para Bravos, então é improvável que ele tenha visto este.

Tyrion could hear the commons shouting out King Joffrey's name. In three years that cruel boy will be a man, ruling in his own right . . . and every dwarf with half his wits will be a long way from King's Landing. Oldtown, perhaps. Or even the Free Cities. He had always had a yen to see the Titan of Braavos.
_{A Storm of Swords, Tyrion VIII, emphasis mine}

• As paredes triplas de Qarth

Novamente, de acordo com sua pergunta, não.

• Os três sinos de Norvos

Nenhuma menção explícita.

• A ponte longa de Volantis

Ele viu a Ponte Longa durante seu cativeiro com Jorah Mormont:

The gateway to the Long Bridge was a black stone arch carved with sphinxes, manticores, dragons, and creatures stranger still. Beyond the arch stretched the great span that the Valyrians had built at the height of their glory, its fused stone roadway supported by massive piers. The road was just wide enough for two carts to pass abreast, so whenever a wagon headed west passed one going east, both had to slow to a crawl.
_{A Dance With Dragons, Tyrion VII}

• O Palácio Com Mil Salas em Sarnath

Nenhuma menção explícita, mas como apontado em esta resposta é improvável, já que foi destruída.

Maravilhas possíveis

• A Grande Pirâmide de Ghis

Ele foi cativo como um escravo no final de A Dance with Dragons fora dos portões de Meereen. Indiscutivelmente, a pirâmide era visível, de modo que pode contar como visitante. Isto é, se você considerar a pirâmide uma das maravilhas.

• A cidade festiva de Chroyane

Em sua jornada pelo rio Rhoyne, eles passaram pela cidade de Chroyane:

The fog clung to them, damp and chilly. A sunken temple loomed up out of the greyness as Yandry and Duck leaned upon their poles and paced slowly from prow to stern, pushing. They passed a marble stair that spiraled up from the mud and ended jaggedly in air. Beyond, half-seen, were other shapes: shattered spires, headless statues, trees with roots bigger than their boat.

"This was the most beautiful city on the river, and the richest," said Yandry. "Chroyane, the festival city."
_{A Dance with Dragons, Tyrion V}

Tyrion também visitou a Long Bridge of Volantis enquanto estava na cidade após ser capturado por Sor Jorah Mormont e levado para lá.

Volantis straddled one mouth of the Rhoyne where the river kissed the sea, its two halves joined by the Long Bridge. The oldest, richest part of the city was east of the river, but sellswords, barbarians, and other uncouth outlanders were not welcome there, so they must needs cross over to the west.

The gateway to the Long Bridge was a black stone arch carved with sphinxes, manticores, dragons, and creatures stranger still. Beyond the arch stretched the great span that the Valyrians had built at the height of their glory, its fused stone roadway supported by massive piers. The road was just wide enough for two carts to pass abreast, so whenever a wagon headed west passed one going east, both had to slow to a crawl.

^{A Dance with Dragons, Tyrion VII}

Vale a pena mencionar que ele não poderá visitar o Palace With a Thousand Rooms, pois foi incendiado por Khal Loso.

Bereft of defenders, Sarnath of the Tall Towers fell to Loso the Lame less than a fortnight later. Not even the Palace With a Thousand Rooms was spared when Khal Loso put the city to the torch.
