Siger Tower, Cultural tower in South Lampung, Indonesia.

Siger Tower is a six-story tower on Bukit Gamping, a limestone hill about 110 metres above sea level west of Bakauheni Port. Its form is a crown of nine tiers in yellow and red, the colours of the traditional siger bridal hat of Lampung's Pepadun community, decorated with carved tapis cloth motifs. A three-colour umbrella (white, yellow, red) marks the top.

Construction began in 2005 and cost Rp15 billion. Governor Sjachroedin Z.P. inaugurated the tower on 30 April 2008, entering with ambassadors from Croatia, Sri Lanka, Japan, Palestine, Afghanistan, Singapore and the Philippines; the ceremony included sirens, a signed plaque and released doves. The tower was intended to precede the planned Sunda Strait Bridge.

The tower takes its name from the siger, the customary crown worn by brides of the Lampung Pepadun community. Its nine tiers stand for the nine languages of Lampung, and the gold-yellow and red finish echoes the golden bridal headdress. Carved ornament reproduces the patterns of tapis, the traditional Lampung cloth.

Climbing to the observation deck offers views over the strait and bay below, with clear days providing the best visibility. Visiting earlier in the day helps avoid crowds and takes advantage of better lighting conditions.

The tower's location serves as a zero point reference for southern Sumatra, functioning as a navigational marker for vessels traveling from Java toward Bakauheni Port. This geographic reference point gives the structure practical meaning for ships navigating the busy strait.
