# Lakehouse Iceberg REST catalog

Connect Foundry to Google Cloud Lakehouse through the [Google Cloud Storage](../google-cloud-storage/index.md) connector. Lakehouse is configured as an Iceberg catalog on a Google Cloud Storage source. The registered virtual tables use Iceberg format and point to tables in that Lakehouse catalog.

## Setup

Lakehouse catalog setup is part of the Google Cloud Storage connector configuration. To configure Lakehouse, add the `Catalog` setting on a Google Cloud Storage source, then select **Lakehouse Catalog**.

:::callout{theme="neutral"}
You cannot use the same Google Cloud Storage source for both a Lakehouse catalog and bring-your-own-bucket (BYOB) Iceberg storage. Create a separate source for each workflow. Configure the Lakehouse source with **Catalog** set to **Lakehouse Catalog**, and configure the BYOB source without a **Catalog** setting.

See the [Google Cloud Storage Lakehouse catalog setup](../google-cloud-storage/index.md#lakehouse-catalog) instructions for authentication, networking, and source configuration details.

## Register virtual tables

To register a table from Lakehouse, open the configured Google Cloud Storage source and register a virtual table with **Format** set to **Iceberg**. See the [Google Cloud Storage registration instructions](../google-cloud-storage/index.md#register-lakehouse-iceberg-virtual-tables) for the full workflow.
