Who was the hall beneath the mound for?

Why build a hall under a mound?

9 scenes · 3 min · Sources · 12

A stone door imitates wood. Colour survives on walls, while broken jars lay outside the entrance. Archaeologists connect these clues with the power and rites of Odrysian kings, but debate how the building was used.

Part of the side stairs at Chetinyova under a modern shelter. Steps were rearranged or added after excavation; their ancient function is debated. This is not the main flight of nine steps.

Part 1 · Antiquity

Stairs beneath the earth

Beneath Chetinyova mound near Starosel stands a stone building. Nine steps lead to a platform. Beyond it lie a corridor and a rectangular antechamber. This is a room before the main round hall. Why build such an elaborate entrance beneath a mound?

Archaeologists excavated the building in 2000. It had already been robbed. Many objects that could help explain what happened inside were missing. Yet doors, walls and broken pots remained.

Part 2 · Antiquity

A great mound among rival kings

The Odrysian kingdom was a state in ancient Thrace. It split, and its rulers competed for power. In 341 BC, the Macedonian king Philip the Second struck a decisive blow against the Odrysians.

One interpretation suggests the great mound could have shown power and ties with earlier kings.

Part 3 · Antiquity

A door made to look like wood

The photograph shows part of a stone door. Projecting circles resemble nail heads. They form a relief: decoration carved to stand out from the stone. The stone resembles a wooden door with boards running across it.

The antechamber entrance had two leaves, the moving panels of a door. The round hall’s door had one. Curved tracks in the thresholds belong to the doors’ moving mechanisms. The doors may have been opened repeatedly during rites.

1 · Stone face
The smooth part is stone. Carved decoration imitates a wooden door.
2 · Carved circles
The projecting circles resemble nail heads. They are part of the carved decoration.
3 · Broken edge
The photograph shows a broken edge of the fragment. It does not tell us when or why it broke.

Part 4 · Antiquity

A round hall with colour

The hall is about five metres across. Ten half-columns attach to its wall rather than standing free. They are called Doric: here they have upright grooves and plain, spreading tops. Above them runs a frieze, a horizontal decorative band. Grooved sections alternate with plain spaces. Traces of blue, black and red survive.

The photograph is modern. The dome stones were reassembled in 2013. The lamps are modern.

1 · Half-column
The column is attached to the wall. The hall has ten such columns; the photograph shows only some of them.
2 · Coloured frieze
The decorative band above the columns alternates grooved sections and plain spaces. Traces of colour survive.

Part 5 · Antiquity

Activity: stone or wood

What are the circles on the door shown here?

  1. Imitation nail heads carved in stone.
  2. Real iron nails in a wooden board.
  3. Coins stuck onto a door.
Why is that?

The door is stone. Its projecting circles are carved into the stone and resemble nail heads.

Correct · Imitation nail heads carved in stone.

Part 6 · Antiquity

Broken pots outside the entrance

Broken pots help us date the building. A piece of a skyphos, a drinking vessel, remained in the antechamber. Fragments of amphoras, large transport jars, lay outside the entrance, beneath the fill blocking it. One interpretation links them to a burial rite before closure.

Comparison with other pots and buildings suggests construction around 350–330 BC. This is a reasoned date range, not an exact year. Philip the Second’s coins came from the embankment, not inside the hall.

Activity: which came first

Put these in order, earliest to latest.

  1. The ancient building is constructed.
  2. Excavation of the building
  3. Reassembly of the dome
Why is that?

Ancient construction preceded excavation. Reassembly of the dome followed excavation. The debate over the ancient date does not alter this order.

Correct order

Part 8 · Antiquity

Who was honoured in the hall?

The hall may have served for burial and honouring a dead ruler. Such a place of veneration is called a heroon.

Whose costly monument was this? The evidence is insufficient to name the ruler. The carved stone shows the labour invested. Honouring a royal family is one possible explanation for that effort.

Activity: match

Match each clue with its description in the story.

  1. Stone door · Resembles a wooden door with nails
  2. Half-columns · Attached to the wall
  3. Amphoras · Transport jars outside the entrance
Why is that?

The door’s carved decoration resembles wood and nails. The half-columns belong to the wall. The amphoras are jars deposited before the entrance was blocked.
