Criccieth Castle dominates the town, standing on a rock overlooking Cardigan Bay.
Little survives of the original building, but the outer defences are still prominent.
The inner bailey contains the earliest remains, including the inner gatehouse, which has two semi-circular towers.
It is thought that the original living quarters were in the south west tower, overlooking the sea, and that the square north tower supported a catapult.

To the south of Y Maes stands Caffi Cwrt, an early 18th century detached stone house where the burgesses held court when rain prevented them meeting in their usual location on the bridge.
The house has been owned by just two families since 1729.
Two medieval strip fields to the rear, Llain Fawr (large strip) and Llain Bella (furthest strip), formed most of the smallholding of Cwrt but were lost when the railway was built.
Nearby, where the slate shop now stands, was a smithy.

On Penpaled Road is a cottage, Penpaled, built in 1820 on a plot lying between two enclosed meadows.
The meadows, Cae'r Beiliaid (bailiff's field) and Llain y Beiliaid (bailiff's strip) were subsequently to form part of the route of both the road and the railway.

Further uphill stand a 17th-century whitewashed cottage, Ty'r Felin, and Foinavon, a yellow pebble-dashed building once owned by the Bird's Custard family.

Morfin, on Tan-y-Grisiau Terrace was used as an office by David Lloyd George whilst he was practising as a solicitor.
 Nearby, Ty Newydd, a mid-16th century house, was originally built to house the estate bailiff.
Criccieth's first council houses on the adjacent Henbont Road were built on land donated to rehouse families made homeless by the 1927 storm.
Three 600-year-old cottages, originally thatched, make up Wellington Terrace.
They are thought to be the oldest in the town.

Ffordd Castell is within the original settlement, Yr Hen Dref, though most of the houses are Victorian.
Ty Mawr, however, originally a smallholding and later a public house, dates from the 16th century, whilst on the opposite side of the street a long stone building, divided into three cottages, Porth yr Aur, Trefan and Cemlyn, dates from 1700.
The Castle Bakery next door features a stained glass insertion above the shop window which depicts bakers at work.
In the past nearby residents could bring their own dough to be baked in the ovens.
By the castle entrance Gardd y Stocs, a small green, was home to the town's stocks, whilst the building that houses the castle information centre was part of the town's guildhall.

The heart of the old town is Y Dref.
It was here that the weekly market was held, and it was also the venue for numerous political meetings.

Edward I granted lands north of the borough to the Bishop of Bangor, and it is thought that Gardd yr Esgob on Lôn Bach formed part of these.
In the 19th century one of the town's abattoirs stood here.
Tan y Graig, a house at the end of a long garden, dates from at least 1800.
Three 16th century fishermen's cottages stand in Rock Terrace.
Named Sea Winds, Ty Canol and Ty Isaf, they have 14th century foundations.

On the green at West Parade stands a shelter donated by Margaret Lloyd George, the wife of the former prime minister.

Muriau on Lôn Fel includes a group of partly 17th century farm buildings set around a square, which were converted into houses by Elizabeth Williams Ellis of Chwilog.
Muriau Poethion contains an early spiral staircase going round a large inglenook fireplace.
North of Ffordd Pwllheli, several mansions are along the lane, now named Lôn Fel Uchaf.
Parciau was once owned by Ellis Annwyl Owen, rector of Llanystumdwy from 1837 to 1846, whilst Parciau Mawr has a notable 19th century hay barn.
Bryn Awelon was the home of David Lloyd George before the First World War, and later of his daughter Megan.
Nearby, on Arfonia Terrace, is Parciau Uchaf, a farmhouse dating from 1829.

Y Gorlan on Ffordd Caernarfon formed part of the small estate of Cefniwrch Bach, a hunting lodge for Edward I at the time the castle was being built, and is thought to have been a tannery in medieval time
